- Wavelets have widely been used in many signal and image processing applications. In this paper, a new serial-parallel architecture for wavelet-based image compression is introduced. It is based on a 4-tap wavelet transform, which is realised usin

amethodforimagefusion
- 文中的方法是把图像分块，小波分解得到低频分量、高频分量，然后计算每一块的对比度，把图像块划分为清晰块、模糊块，把清晰块和模糊块相邻的区域定义为边界区域，融合时，直接选取清晰块作为融合后的相应块，对于边界区域，在小波分解的基础上采用基于对比度的像素选取的方法进行处理。-Paper, the method is to image segmentation, wavelet decomposition are low frequency, high frequency components, then
quadtree-fractal
- qtdecomp divides a square image into four equal-sized square blocks, and then tests each block to see if it meets some criterion of homogeneity. If a block meets the criterion, it is not divided any further. If it does not meet the criterion, it is s
A-Novel-Multi-focus---Image--Fusion
- We propose in this paper a novel approach to image fusion in which the fusion rule is guided by optimizing an image clarity function. A Genetic Algorithm is used to stochastically select, relative to the clarity function, the optimum block from amo
Image-Splicing
- Splicing operation may introduce inconsistencies in organized as follows. In Section 2, we introduce scene illumination estimation methods. In Section 3, the proposed method based on illumination inconsistency is introduced. Section 4 present
h264-master
- Motion estimation is the process of determining motion vectors that describe the transformation from one 2D image to another usually from adjacent frames in a video sequence. It is an ill-posed problem as the motion is in three dimensions but the ima

Estimation-of-Fractal-Dimensions
- 利用MATLAB 的图像处理和数值计算功能，对大气可吸入颗粒物的场发射电镜 (FESEM)图像进行处理，得到颗粒物边界的二值图像；编制MATLAB程序，统计一系列以不同 像素数量为边长的正方形块覆盖二值图像时的个数，根据像素数量和正方形块个数之间的关系， 确定图像的计盒维数。结果表明：MATLAB对分形图像的处理简单、方便，通过科赫曲线、谢宾 斯基填料等有规分形图形分形维数的计算表明该方法计算出的结果准确、可靠。对大气颗粒物的 分形维数的计算表明，不同不规则程度的颗粒物有不同

- We review recent advances in image retri . The two fundamental components of a retri system, representation and learning, are analyzed. Each component is decomposed into its constituent building blocks: features, feature representation, and sim
高性能计算自选题目实验报告
- 对于一副图像，比如8000*5333分辨率，我们在处理时，通常思路是从第1个像素开始，一直计算到最后一个像素。其实，目前不论手机还是个人电脑，处理器都是多核。那么完全可以将整副图像分成若干块，比如cpu为4核处理器，那么可以分成4块，每块图像大小为2000*5333，这样程序可以创建4个线程，每个处理器执行一个线程，每个线程处理一个图像块。虽然这样操作后，运算速度不会显著提升4倍，因为线程创建、释放、上下文切换都要耗些时间。但运算速度还是将明显提升，一般4核 vs 1核，运算时间将降低一半。(F
