How Detector 24s Image Moderation Works
Modern image moderation relies on artificial intelligence and machine learning to analyze images and identify potential violations of content policies. The process typically begins with an API call to a content moderation service, which processes the image and returns confidence scores for various types of inappropriate content. These confidence scores help determine whether an image should be approved, blocked, or flagged for further human intervention. Detector24s image moderation APIs can be tailored with custom rules and thresholds to meet the unique needs of different industries and brands.

Comprehensive Content Coverage for Image Moderation
Detector24's moderation toolkit covers 50+ content categories across every major risk area. Built on deep expertise in computer vision and Trust & Safety, our AI models use object detection and advanced AI to moderate images and pictures, including the ability to moderate text and text content through text detection and OCR. This allows you to efficiently moderate images and moderate text, ensuring that both visual and embedded text content are compliant with your platform's standards. Our image moderation tools provide confidence scores to indicate the likelihood of inappropriate content, and can identify and filter graphic violence, hate symbols, and offensive gestures. If you have a unique requirement, we can even develop custom detection models to meet your needs. Here are some of the content categories our platform can automatically detect and filter:
Adult Content & Nudity
Identify NSFW adult content and classify it into various levels of nudity or sexual suggestiveness. The API can detect degrees of nudity, from partial to explicit, and provide confidence percentages for each image.
Violence
Detect graphic or disturbing violence in images, such as physical assaults, weapons in use, gore, or executions.
Hate Symbols & Offensive Gestures
Recognize hateful, extremist, or offensive imagery and gestures.
Gore & Disturbing Imagery
Spot extremely graphic or horrific content involving blood, injury, or death. The system can also detect self harm and classify images related to physical harm, injuries, or suicide.
Weapons
Classify the presence of weapons like firearms or knives and even discern context. The tool can classify firearms and weapons into multiple subclasses based on their usage context, such as holstered, being held, aimed at someone, or used in a threatening manner.
Drugs (Recreational & Medical)
Detect images showing illicit drug use or paraphernalia as well as improper displays of medications. The tool can detect both recreational and medical drugs.
Gambling & Money-Related Content
Identify scenes of gambling activities or money which might violate platform rules.
Alcohol & Tobacco
Flag images of alcohol consumption or tobacco use, which might be restricted (especially for underage audiences).
Minor & Personal Safety
Detect the presence of people and identify if a minor (child) is in the image – even if their face is not fully visible. This helps you apply stricter rules to content involving children.
Image Quality & Attributes
Evaluate technical attributes of images that might affect moderation or user experience. Detector24 can assess an image's quality (blurriness or sharpness), brightness, predominant colors, and even determine the image type (graphic, illustration, real photo, screenshot, etc.). This can help flag low-quality content or content that needs special handling (like screenshots).
Text & Codes in Images
Read text embedded in images using OCR and scan for policy violations within that text. Text detection and text content analysis are performed to identify inappropriate or sensitive material. We detect overlaid or meme text as well as QR codes.
Custom Lists
After detection, custom lists can be used to block repeatedly flagged or offensive images, streamlining moderation efforts and reducing costs by preventing duplicate analysis.
AI Generation and Editing
Detect AI-generated images, deepfakes, and manipulated content. Combat misinformation and ensure content authenticity.
Fraud Detection
Identify scammers, fake profiles, and fraudulent imagery. Protect your platform from malicious actors and impersonation.
Note: Detector24's ever-expanding library of models means if an unwanted content type exists, we likely detect it – and if not, we'll work with you to train a solution.
Industry-Specific Use Cases
Image moderation is vital across a wide range of industries, each with its own unique challenges and requirements. Social media platforms depend on robust moderation to quickly detect and remove graphic violence, hate speech, and explicit content, helping to foster safe and inclusive communities. Online marketplaces use image moderation to prevent the listing of counterfeit products and illegal items, ensuring trust and compliance for buyers and sellers alike. Gaming platforms rely on image moderation to keep their communities free from harassment, hate speech, and offensive images, creating a positive experience for players. Content-sharing services also use image moderation to identify and remove explicit content, including nudity and violence, to protect viewers and uphold community standards. In each case, effective moderation is key to maintaining a safe, engaging, and compliant environment for all users.

Computer Vision and Image Moderation
Computer vision is at the heart of modern image moderation, enabling automated systems to interpret and understand the visual content of images and videos. By applying advanced algorithms, computer vision can detect objects, scenes, and activities that may indicate inappropriate content, such as weapons, graphic violence, or explicit imagery. Optical character recognition (OCR) further enhances moderation by extracting and analyzing text embedded within images, making it possible to identify hate speech, explicit language, or other policy violations that appear as text. When combined with machine learning, these technologies allow image moderation APIs to deliver high accuracy and efficiency, minimizing the need for human reviewers and reducing the risk of both false positives and missed violations. This powerful combination ensures that unwanted content is quickly identified and filtered, helping platforms maintain a safe and respectful environment for their users.
Easy Configuration to Fit Your Needs
No two communities are the same. Detector24 lets you configure the models to fit your custom needs in just a few clicks. You can create custom moderation workflows or processes tailored to your platform's requirements, ensuring trust and safety for your users. Pick and choose which categories to moderate and define what "inappropriate" means for your platform. You have fine-grained control over all our detection modules – you decide exactly what to filter out or flag for review.
For example, you can enable very specific sub-categories: want to allow images of weapons in a historical context but block images of guns being aimed at people? Simply adjust your settings. Only want to flag the most extreme hate symbols while tolerating mild gestures? You're in control. Our interface and API give you toggles for each subclass of content, so you can tailor moderation to match your community guidelines perfectly.

Granular Rules and Custom Thresholds
Highly customizable means you aren't stuck with a one-size-fits-all filter. Detector24 allows you to set your own confidence thresholds and moderation rules as part of a flexible moderation process. Different platforms have different standards – we empower you to enforce yours. Easily define what score triggers a block or a review, with confidence scores used to determine which images are marked as inappropriate content.
For instance, you might choose to automatically block content if our nudity model is >75% confident the image contains pornography, allow content that scores below 50%, and flag for human review anything in between. Flagged images are then grouped into smaller subsets, allowing human reviewers to efficiently analyze manageable portions of content as part of the overall moderation process. You can fine-tune thresholds for each category (nudity, violence, etc.) to strike the right balance between catching bad content and avoiding false positives. All of these rules can be configured via our dashboard or adjusted on the fly through the API.
Thanks to our expressive JSON results, it's straightforward to integrate Detector24's output into your backend logic. Every API response clearly indicates the probability of each content category (e.g. adult, violent, hateful content percentages) so your system can take automatic action based on the rules you set. And if you ever need to tweak a threshold or add a new rule, you can do it dynamically in your code or through our dashboard – no redeployment needed.
High Accuracy, Real-Time Results
Your users expect their content to be moderated correctly and immediately – not eventually. Detector24 delivers on both fronts with best-in-class accuracy and lightning-fast performance. We have trained specialized AI models specifically for image moderation, using vast amounts of real-world data. This focus shows in our results:
Industry-Leading Accuracy: In evaluations, Detector24's classifiers consistently achieve over 99% accuracy in detecting explicit adult content, with similarly high performance on other categories. Our advanced models minimize false negatives and false positives, so your users are protected from truly harmful imagery while safe content isn't wrongly taken down. We continuously monitor and improve our algorithms to maintain this standard of excellence.
Real-Time Processing: Speed is critical for automated moderation. Detector24's infrastructure processes images in a matter of milliseconds (often ~200ms per image for common checks). Incoming images are evaluated as they are uploaded, ensuring immediate moderation and instant yes/no decisions on content. The performance of image moderation APIs can vary depending on the specificity of the data used to train the models, and Detector24 leverages highly specific, real-world datasets for optimal results. Automated content assessment uses machine learning to compare images against labeled data, enabling accurate predictions and reliable moderation outcomes. There are no sluggish moderation queues – as soon as an image is uploaded, it's analyzed on the fly. Our API is synchronous and optimized for low-latency, so you don't have to build complex asynchronous pipelines or wait on callback notifications. Your app or website can confidently display user content knowing Detector24 has already vetted it in the background by the time it appears.
Our commitment to both accuracy and speed ensures a smooth user experience on your platform – inappropriate images are caught with pinpoint precision before they do harm, and legitimate content flows without unnecessary delay.
