彩色图像处理
- 比较对彩色图像CSimage4.bmp仅进行I分量平滑处理和对H、S、I三个分量都进行平滑处理后的图像情况。(Compared with the color image CSimage4.bmp, only the I component smoothing processing and the H, S, I three components are smoothed after the image processing.)
实验一 图像颜色特征提取
- stricker和0reng0提出了颜色矩的方法，颜色矩是一种简单有效的颜色特征表示方法，有一阶矩(均值)、二阶矩(标准差)和三阶矩(斜度)等，由于颜色信息主要分布于低阶矩中，所以用一阶矩，二阶矩和三阶矩足以表达图像的颜色分布，颜色矩已证明可有效地表示图像中的颜色分布。 对彩色图像进行颜色矩特征参数提取，首先要将RGB彩色图像转换到HSV颜色空间，对图像的H、S、V颜色分量图像分别提取一阶颜色矩、二阶颜色矩、三阶颜色矩。(Image color feature extraction and f
