Visual discomfort is one of the most frequent complaints of the viewers when watching stereo images or videos. It has been the subject of considerable research in relation to stereo display system. To predict the effects induced by three-dimensional contents on visual discomfort, a new objective visual comfort assessment (VCA) method of stereo image is proposed based on scene mode classification....
Saddle points formed through morphologic erosion and existing between adjacent connecting objects in 2D images have been applied for segmenting purposes. In this article, a new approach is presented for searching the saddle points in 2D images using mathematic programming restraints for the purpose of ultimately separating the connecting objects. By combining the pixel distribution information in...
Semantic image segmentation (SIS) is one of the most crucial steps toward image understanding. In this paper, a novel framework to enable SIS is proposed by modeling images automatically. The statistical model for an image is automatically obtained by using a finite mixture model to approximate the underlying class distributions of image pixels. To accurately characterize the principal visual properties...
In order to solve the problem of inconsistent color appearance between different views, and subsequently influences on multi-view video coding, a color correction algorithm of multi-view video based on depth segmentation is proposed in this paper. Firstly, depth information in each view is calculated. Then, background and foreground region are separated with the depth information. Finally, correction...
A content-adaptive color correction algorithm for multi-view video is proposed due to variation in lighting or camera parameters. We first establish color correction property between the target image and source image. Then color correction matrix can be obtained by global correction or preferred region matching correction. Finally, video tracking technique is used to correct multi-view video sequences...
Inconsistent color between different viewpoints is a serious problem in multi-view image processing. A multi-view image color correction method is proposed. We first estimate whether global correction satisfied for the target image and source image. If no global correction is satisfied, image segmentation and Karhunen-Loeve (K-L) transform are performed. Then, local mapping relations between target...
