some fast feature extraction algorithms are addressed for joint retrieval of images compressed in JPEG and JPEG2000 formats. In order to avoid full decoding, three fast algorithms that convert block-based discrete cosine transform (BDCT) into wavelet transform are developed, so that wavelet-based features can be extracted from JPEG images as in JPEG2000 images.

Three algorithms are described: energy-spectrum image auto focusing evaluation function, image merging based on the adaptive selection of standard image and sum-modified-Laplacian (SML) operator for multi-focus image fusion. The algorithms have been applied successfully to CMIAS medical micro-optical image analysis system and testified to be feasible and effective. )

说明：  图像超分辨率是指从一序列低分辨率观测图像中重建高分辨率图像。图像超分辨率充分利用了各帧图像 间相似而又不同的信息。(Compared with the model derived from Kolmogorov spectrum, the new model introduces more complete transcendent constraints and is more similar to the physical characteristics of atmospheric turbulence.)

说明：  ENVI软件标准格式的高光谱遥感图像含有两部分：一个是高光谱图像 '*.img '，另一个是遥感图像头文件 '*.hdr'，该文件记录了遥感图像的信息，如图像尺寸、波段数、数据类型和大小端等。如果缺少头文件，将无法对遥感图像进行读取，因此头文件十分重要。 在Matlab中，将利用函数multibandread()对多波段（高光谱/多光谱）图像进行读取。(The hyperspectral remote sensing images of ENVI software standard format contain two parts: one is hyperspectral image'*.img ', the other is the remote sensing image header file'*.hdr', which records the information of remote sensing image, such as image size, band number, data type and size end, etc. If there is no header file, it will not be able to read remote sensing images, so header files are very important. In Matlab, multibandread () is used to read multiband (hyperspectral / multispectral) images.)
