Abstract:

A subregion-based image parameter recovery system and method for recovering image parameters from a single image containing a face taken under sub-optimal illumination conditions. The recovered image parameters (including albedo, illumination, and face geometry) can be used to generate face images under a new lighting environment. The method includes dividing the face in the image into numerous smaller regions, generating an albedo morphable model for each region, and using a Markov Random Fields (MRF)-based framework to model the spatial dependence between neighboring regions. Different types of regions are defined, including saturated, shadow, regular, and occluded regions. Each pixel in the image is classified and assigned to a region based on intensity, and then weighted based on its classification. The method decouples the texture from the geometry and illumination models, and then generates an objective function that is iteratively solved using an energy minimization technique to recover the image parameters.

Abstract:

The present disclosure provides method and apparatus for providing video recommendation. At least one reference factor for the video recommendation may be determined, wherein the at least one reference factor indicates preferred importance of visual information and/or audio information in at least one video to be recommended. A ranking score of each candidate video in a candidate video set may be determined based at least on the at least one reference factor. At least one recommended video may be selected from the candidate video set based at least on ranking scores of candidate videos in the candidate video set. The at least one recommended video may be provided to a user through a terminal device.
