In this paper, we present an efficient hybrid image compression method. According to Human eye sensitivity, It is not sensitive to gray-scale error, but the human eye is particularly sensitive to the image edge features, through we research strengths and weaknesses of the fractal image coding and SPIHT(set partitioning in hierarchical trees) algorithm, proposed a hybrid algorithm based on SPIHT and...
The key to extracting the edge characteristics of grain bags in the grain reserve warehouse was image segmentation. In practice, the quality of the selected segmentation algorithm directly determined the effect of the bags image segmentation. According to the characteristic of the grain warehouse scene an improved segmentation algorithm based on combining maximum between-cluster variance with edge...
