This is my ERROR. My image dimension is about 667*535. But in error it replaces x values with y and y values with x. I don't know why it is replace x and y values

Attempted to access RGB(548,493,1); index out of bounds because size(RGB)=[535,667,3].

Error in connect (line 109) red(j)=RGB(x,y,j);

A very common mistake is to confuse rows and columns with x and y.

Images are arrays and thus the first index is the row, and the second one is the column. So if you ever refer to yourImage(x, y) you could well go out of bounds or certainly will have your operation transposed (rotated 90 clockwise or counterclockwise). You need to use yourImage(y, x), NOT yourImage(x, y)!
