Color_digital_image_sharper
- 分别采用RGB模型和HIS模型对图像imageLane.bmp进行锐化,并比较锐化的效果是否相同(两锐化后的图像相减)。-Using RGB model respectively for imageLane image and HIS model for sharpening, BMP, and compared the effect is the same sharpening (two sharpen the image subtraction).
JPEG_compression_image.m
- 利用Matlab编程实现对lena.bmp灰度图象进行QF=50和QF=40的压缩和解压缩,比较二者的PSNR,并且利用霍夫曼编码模拟信道中传输图象。通过了Matlab2009A测试。-Using Matlab program to compress and decompress the gray image Lena.bmp at QF = 50 and QF = 40,as well as comparing the result of two situation.Then using Hu
GUI-drawing-board
- Matlab鼠标画图,用pop-up menu选择画图标记,颜色edit记录鼠标坐标 但是功能比较简单,只能画线,不能画矩形、椭圆等 其中一个难点就是:拖动鼠标的过程中如何显示矩形/椭圆的轮廓,并且轮廓跟着鼠标指针移动。 程序的亮点: 1、可选择点、线、矩形、椭圆进行画图; 2、可选择marker、LineTyple进行画图; 3、可选择画图颜色; 4、可实时显示鼠标指针当前坐标; 5、可清除画板; 6、可保存画好的图(bmp、jpg、gif); 7
