In order to improve the precision of 3D reconstruction, a new composite coding way based on structure light is proposed. In this paper, color stripe pattern is used as basic coding element and intensity properties are introduced for every color stripes to design coding pattern. This coding pattern can be used to extract stripe peak and edge information on sub-pixel level. In the reconstruction we...
This paper research the use of computer visual and image information collected preprocessing based on pattern recognition of soybean Nitrogen element detect. When Nitrogen elements of the soybean plant changes, color and texture will be characteristic. By nurturing and collecting samples, This work analyzed the characteristics determine preprocessing, established a preprocessing system model. The...
A scheme for auto classification of skin symptom is introduced in this paper. It classifies different skin symptoms based on the principle of least Mahalanobis distance. Skin images with symptom to be identified will be preprocessed at first. Basic operations of preprocessing includes color space transformation, image segmentation based on threshold by self-adapting method, image post-processing by...
Losing a packet will cause losing a whole frame in high compression and high payload video communication such as wireless low bit rate video transmission. In this paper, we present a novel technique which can deal with the problem of error concealment for whole frame losses. The proposed technique exploits objects motion information from video by combining gray and color optical flow methods to reconstruct...
Most automatic speech recognition systems have concentrated exclusively on the acoustic speech signal, and therefore they are susceptible to acoustic noise. The benefits from visual speech cues have motivated significant interest in automatic lip-reading, which aims at improving automatic speech recognition by exploiting informative visual features of a speaker's mouth region, which means speaker...
