An image classification method based on wavelet transform was brought up, and it adopted the human visual features model and analyzed the image parameter characteristics in smooth and texture regions. It put up optimum carrier image selecting method of original image to be hidden while analyzing the differences between the carrier and being hidden image. On the premise of setting a threshold, it made...
Based on analysis on video retrieval issues among different time scales, a dynamic time warping (DTW) optimal matching algorithm is proposed in this paper. Firstly the sub-segments detection algorithm was used to separate the video into several consecutive sub-segments; furthermore, the video similarity matching algorithm on the basis of sub-segments was used to implement the retrieval process. The...
Two-dimensional electrophoresis gel image is a popular method used in protein studies. The image is often affected by image brightness which might result in inaccurate diagnostics. High dynamic range (HDR) takes a set of photographs taken in different range exposures and converges all into one single image containing details from a range of brightness giving a more accurate image to be used for improving...
