In the procedures of image acquisition, compression, and transmission, captured images usually suffer from various degradations, such as low-resolution and compression distortion. Although there have been a lot of research done on image restoration, they usually aim to deal with a single degraded factor, ignoring the correlation of different degradations. To establish a restoration framework for multiple...
Illumination condition is one of the most important factors that affect the face recognition performance. Face image illumination quality assessment can predict the face recognition performance under various illumination conditions, which will improve the accuracy and efficiency of the face recognition system. However, the quality scores calculated by the existing methods are weakly correlated with...
Content-Based Image Retrieval (CBIR) characterizes the image content by extracting visual features, and measures the similarity according to the distance between the two features. This paper adopts CBIR to perform automatic tongue color analysis of Traditional Chinese Medicine (TCM). Firstly, we extract the visual features of tongue images to be analyzed, especially the color features; and then retrieve...
