Online 2D Image Quality Assessment (IQA)
Introducing an innovative online app that assesses the quality of 2D images using cutting-edge deep learning algorithms; a deep Vison Transformer (ViT) model.
All of the computing is done right on the edge of the client, which means you can easily use the app offline once it is loaded and evaluate images in a variety of formats, including JPEG, PNG, and others.
With this free app, you can be confident that your images will be evaluated precisely and accurately, allowing you to make informed decisions about the quality of your digital content. Whether you're a professional photographer, graphic designer, or just someone who wants to make sure their images are of high quality.
So why wait? Try the app today and experience the power of deep learning for yourself!

Online Quality Evaluation for Stereoscopic images without reference
The first online app for assessing the quality of stereoscopic 3D images. The metric is based on a deep Convolutional Neural Network (CNN) and does not require pre-processing; it should work with any image resolution greater than 32 x 32 pixels, and it supports all image formats (e.g., BMP, PNG, JPG, GIF ...etc).
Click on the link below to test the app, please note that the app does not record or save any user's data/images but a feedback is appreciated.
Online facial analysis with Javascript
The simplest way to deploy image processing applications online is to use javascript (on-edge execution). If there is an API and we only need to call the functions, it will be even easier and faster. I used the face-analysis API in this case to deploy online face analysis app from the user camera video stream. Please try the live demonstration (link below), the app does not record or save any user's data/images.
