[matlab]修改图片尺寸并保存

img = imread('test3.jpg');
i = imresize(img,[96,128]);
imwrite(i,'vehicle.jpg');

1、imresize改变图片尺寸

B = imresize(A,scale)

B = imresize(A,[numrows numcols])

[Y,newmap] = imresize(X,map,___)

___ = imresize(___,method)

___ = imresize(___,Name,Value)

2、imwrite保存图片

imwrite(A,filename)

imwrite(A,map,filename)

imwrite(___,fmt)

imwrite(___,Name,Value)
