ImproveDDA
- 改进的DDA算法，不论方向输出像素点，即给出线段两端点，就得到唯一的线段像素值-improved algorithm, regardless of the direction of the output pixel, which is given segment ends, on the line is the only value of the pixel
kmedfilter
- K近邻中值（均值）滤波器 1) 以待处理像素为中心，作一个m*m的作用模板。 2） 在模板中，选择K个与待处理像素的灰度差为最小的像素。 3） 将这K个像素的灰度均值（中值）替换掉原来的像素值。 -K-nearest neighbor median (mean) a filter) for the pixel to be addressed, for a m * m role template. 2) In the template, select and K-pending p
PVEInterpolation
- Partial volume correction method using reverse diffusion interpolation This function implements a reverse diffusion scheme to interpolate images to correct for partial volume effect. Under the assumption that the pdf is about the size of the pix

rgb_picker
- 基于wtl的屏幕象素拾取器，显示当前鼠标下象素的r,g,b值-based wtl pick up the pixels on the screen, showing the current pixel mouse under the r, g, b value
latlong2spherical
- Environment map conversion procedure using generic pixel-to-ray and ray-to-pixel primitives. You need this equirectangular environment map image: latlong.ppm. The output is a spherical mirror ball image spherical.ppm that you can also use in the form
如何对象素点着色java
- 如何对象素点着色java-how to point pixel shader java
zsfk
- 如果顺序选取像素点进行信息隐藏，势必会造成图象各部分统计特征的不一致，而导致了严重的安全问题。载体的第一部分和第二部分，也就是修改的部分和没有修改的部分，具有不同的统计特性，增大了攻击者对秘密通信的可能性。为了解决这个问题，可以随机间隔选取像素序列。此嵌入与提取算法与前面一小节所描述的顺序隐秘的算法基本相同，只是在选取像素序列时不再顺序而是随机间隔的选取。-order if selected pixel information hidden, it is bound to be part of
BundleAdjustment
- 立体影像对的光束法严密解求外方位元素：已知控制点的左右影像像点坐标和物方空间坐标，解求左右影像的外方位元素。-three-dimensional images of the bundle closely to Solve exterior orientation elements : known control points around the image pixel coordinates and objects to space coordinates solution for image
