Description: hanks for downloading this code. This VB Project shows you how to make forms with \"rounded rectangle\" shape. It also shows you how you can reduce the size of your programs with a GUI by using blocks of images and absolutely positioning and stretching them to create a dialog box, rather than making the whole dialog box in a graphics program and setting it as the Picture property of the Form. Another advantage of using image blocks is that you can resize this form to virtually any size and the effect will still be the same.

Description: 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 using some FIFO memory modules implementing a pixel-level pipeline
architecture to compress and decompress images. The real filter calculation over 4 · 4 window blocks is
done using a tree of carry save adders to ensure the high speed processing required for many applications.
The details of implementing both compressor and decompressor sub-systems are given. The primarily analysis
reveals that the proposed architecture, implemented using current VLSI technologies, can process a
video stream in real time.-Wavelets have been widely used in many sign al and image processing applications.

Description: 分形用于图像压缩编码,分形编码非常费时，大部分时间浪费在给每个range块寻找合适的domain块，但如果减少搜索domain块的范围，编码速度将有很大提高。所以编码时用快限制分形编码,把图像分成4小块，每块中的range块只在这块中寻找domain块。-for fractal image compression coding, fractal coding is very time-consuming, most of the time wasted in each range block to find a suitable domain block, But if the search domain blocks to reduce the scope of coding speed will be greatly improved. So fast coding using fractal coding restrictions, the image is divided into four small pieces. every piece of the range block only find in this domain block.

Description: In this paper the watermarking programs based on the
discrete cosine transform (DCT) domain DC component (DC) is
adopted. Through adjusting the block DCT coefficient of the image the
watermarks are hidden. And blocking the selected image according to
8×8 pixel, then dividing the selected image into four non-overlapped
sub image blocks according to 4×4 pixel, and thus the watermarks are
embedded through adjusting their DCT coefficient. The experimental
results show that the method has strong robust.

Description: 二值图像数字水印算法的一般方法，然后在此基础上给出了一种基于分块DCT的自参照直流系数盲检测二值水印方法。-A blind binary image digital watermarking algorithm is proposed in the DCT domain. The algorithm uses the correlativity of the inter-blocks DC components based on blocked DCT with binary image. No original binary image is needed when detecting the watermark. The algorithm is realized with the efficient and practical programming tools MATLAB, The effect of the corresponding parameters is analyzed in detail.
