imagecodingexample
- 处理图像lena.bmp,并画出各图像的灰度层次的分布图,并对256位和16位信源数据进行霍夫曼编码-lena.bmp image processing and paint images of the gray level of distribution map as well as 256-bit and 16-bit data source coding Hoffman
lena
- lena等常用的图象标准测试图片若干,BMP格式
standard_test_color
- 标准彩色测试图像,包括airplane,baboon,couple,girl,lena,peppers等的bmp,tiff以及jpg格式
imagetest
- 绘制一个多通道图像的灰度直方图,默认处理文件是lena.bmp-Draw a multi-channel histogram of the image, the default processing of documents is lena.bmp
decoderprog
- fractal image compression of gray scale images.... only works for square images... try with lena.bmp a gray scale one.... good compression ratio acheived
Lena
- 使用VC++显示BMP图像,是最基础的部分。-show BMP picture.
256togray
- 本源代码实现256色彩色图像像灰度图像的转换。-256 image to gray image.
change-bmp-to-raw
- 用c将bmp文件打开并转成raw格式,图像是lena-use c++ to open bmp images and change it to raw images.
waveletfigure
- 程序是下面这样,但只能处理长宽一样的方形图像,灰度和彩色图像都可,要用其他图像只需把Lena.bmp改为其他图像,但图像要保存在m文件所在路径下-wavelet figure process
1.6 尺度不变特征提取
- im=imread('lena.bmp'); im=double(im); [ pos, scale, orient, desc ] = SIFT( im); 注意:要转换成double型(Im = imread (' Lena. BMP '); Im = double (im); [pos, scale, Orient, desc] = SIFT (im); Note: to convert to double)
