L = GETWINDOWS(A,[ROW,COL],WSIZE,INCLUDE)
| Input | |
| A | Dataset containing feature images |
| INDEX | Index vector of target pixels in the images (Objects in A) |
| ROW | Column vector of row-coordinates of target pixels |
| COL | Column vector of column-coordinates of target pixels |
| WSIZE | Desired size of rectangular window around target pixels |
| INCLUDE | Flag (0/1), indicating whether target pixels should be included (1,default), or not (0) in result. |
| Output | |
| L | Index in A of window pixels |
This routine generates all objects in a dataset constructed by image features that are in a window of size WSIZE around the target pixels given by INDEX, or by [ROW,COL]. If WSIZE is omitted or empty ([], default), just the 4 4-conntected neighbors of the target pixels are returned. L points to the window pixels, such that A(L,:) is a dataset of the corresponding objects.
