You can use MATLAB®and Simulink®together to explore implementation options for your FPGA image processing algorithms. Options include partitioning between hardware and software, adding hardware micro-architecture, and fixed-point quantization. At each step, you can simulate the new version and compa...

image steganography using DCTI want to hide image under cover image using DCT. But while doing quantization step, most of dct coefficients of cover image become zero . So should i avoid quantization step during image steganography or choose a cover image of much larger size to embed each bit,...
In this post, we are going to share with you, the MATLAB implementation of Color Quantization and Color Reduction of images, using intelligent clustering approaches: (a) k-Means Algorithm, (b) Fuzzy c-Means Clustering (FCM), and (c) Self-Organizing Map Neural Network. The implemented code,...
使用MATLAB实现图像的识别,这是MATLAB官网上面的例子,学习一下。 http://cn.mathworks.com/help/vision/examples/image-category-classification-using-bag-of-features.html 这个算法叫做a bag of features approach for image category classification,用于识别小图片里面的是小狗、小猫、还是火车、船等。

一、量化的基本思想(Quantization) 我们现在可以开始学习会引起误差的主要步骤,那就是量化。这也是进行很大压缩的一步,没有量化, 我们不可能做到很大压缩。我们先回忆一下之前学过的步骤,首先从一个 8 x 8 图像开始的,然后将它进行DCT变换,变换后我们得到了变换系数T(u,v)。为了方便理解,我们再把变换系数的公式...
二十三、Image Sampling and Quantization 图像采样和量化 二十四、Image under-sampling and aliasing 图像采样不足和混叠 Aliasing is an artifact in an image that can appear as a result of reducing an image’s size. 锯齿是图像中的一种伪影,可能是缩小图像尺寸的结果。 When the size of an image is...
It also reduces the time required for images to be sent over the Internet or downloaded from Web pages.JPEG and JPEG 2000 are two important techniques used for image compression.Keywords: Image Compression, JPEG, DCT, Fourier transform, Spatial Domain, Frequency Domain, Quantization.INTRODUCTION...
