inread<BR>rgb2gray<BR>double<BR>然后滤波 要先进行图像格式的转换 先转化成double用rgb2gray实现 不用管图象的格式,你就直接在读入的时候读入BMP 格式的文件,然后就可以加噪声和去噪声了.傅里叶变换imshow()
imshow(A,[])中的[]是什么意思?为什么要用[];请赐教。 IMSHOW(I,) displays I as a grayscale intensity
image, specifying the data range for I. The value LOW (and
any value less than LOW) displays as black, the HIGH (and any
value greater than HIGH) displays as white, and values in
between display as intermediate shades of gray. IMSHOW uses
the default number of gray levels. If you use an empty matrix
([]) for , IMSHOW uses ; the
minimum value in I displays as black, and the maximum value
displays as white.
