Contrast of image plays an important role in image perception quality and is also susceptive to various factors during image acquisition process. However, only a few image quality evaluation algorithms have been focused on the contrast-changed image quality assessment (IQA), and none of these methods belongs to blind IQA algorithms. Therefore, they cannot be applied to the case when the reference...
Contrast plays an important role in human visual perception while it is usually unsatisfactory due to various factors in the acquisition process of images. With numerous approaches proposed to enhance contrast, less work has been dedicated to contrast changed image quality assessment (IQA). In this work, we propose a quality assessment model based on dual-path feature-difference, which uses a dual-channel...
News video caption, which carries main contents of related news story, plays an important role in content-based video analysis and retrieval system. In this paper, the convolutional neural network (CNN) is used to the recognition of chinese caption text in news video. First, the color and edge feature are used for caption location. Then, the segmentation combined Otsu and K-means clustering algorithm...
Although there exists some methods for coin detection and recognition, it is still a challenging task, especially for coins in natural scene. This paper proposed a method to detect and recognize the coins in natural scene. In the detection part, the Hough detection method is applied to detect the coin areas in the images. Then radius ratio, color feature and relative position constraints are used...
