Abstract: A method for generating alpha channel information related to a person, the method may include generating the alpha channel information related to the person by an alpha channel neural network; wherein the alpha channel machine learning process is trained using ground truth alpha channel information that is associated with background information; wherein the ground-truth alpha channel information is generated by: obtaining input images of the person; wherein each image comprises the person and an arbitrary background; repeating, for each input image of the input images, converting the input image, by a portrait matting predictor, to (a) a first colored background image that comprises the person and a background of a first color, and (b) a second colored background image that comprises the person and a background of a second color; wherein the first color differs from the second color.

Abstract: System, device, and method of image processing, particularly utilizing machine learning and computer vision. A user selects a particular shirt from an online catalog; and instead of seeing an image of the shirt on the shelf or being worn by a model, the system generates and shows to the user an image of that particular shirt being virtually dressed by that particular user. The user requests the system to show search results for blue pants; and instead of producing generic images of blue pants, on the shelf or worn by various models, the system generates user-tailored search results that shown various types of blue pants being virtually worn by the user himself, or virtually worn by a particular other person that is selected by the user. The system enhances the product image by correcting it and by adding realistically-looking shading and wrinkles.
