为什么我使用函数roicolor一直报错啊?图片像素为240*135
程序如下：I=imread（'bird.jpg'）;
imshow(I);
BW=roicolor(I,100,55)；
之后就会报“??? Error using ==> roicolor
Images with dimensions greater than two are not supported.“这个错误

BW = roicolor(A,LOW,HIGH) returns a region of interest
selected as those pixels that lie within the colormap range
[LOW HIGH]:

BW = roicolor(A,low,high) {MOD}图范围为[low high]，返回这些像素选择区域。BW为大小和A相同的数组，若A中元素值在[low high]范围内，则返回值1，否则返回0.
重新设置2个0~1直接的参数试试
