图像像素距离与空间距离变换公式的求解。计算目标运动的速度和对应的像素变化的关系，很有用。-Image pixel distance and spatial distance transformation formula solving. Change of speed for calculating the target motion and the corresponding pixels, very useful.

VC编程中如何在界面上实现3D文字。 首先启动VC生成一个新的基于对话框的项目，命名为3Dtext，在对话框中重载OnPaint()函数，具体实现的思想是通过CDC：：SetTextColor（）分别设置文字的颜色为高亮（3DHILIGHT）和阴影（3DSHADOW）的状态下显示文字；同时注意在两次显示文字时要错开一个像素，这样才能达到预期的效果。-VC programming interface, the 3D text. The idea is to start the VC to ge

Median filter replaces the intensity value in each pixel by the local median taken over a local n x m processing window where is a local m x n window around the pixel (x,y) in the image g (to be processed), and MED is the median value taken over the

In this paper, a fast and memory efficient version of set partitioned embedded block (SPECK) image coder is proposed. Due to use of linked lists, SPECK algorithm, requires large run-time memory, making it unsuitable for memory constrained portable mu
