WitrynaBW must be a binary image where nonzero pixels belong to an object and 0 pixels constitute the background. The following figure illustrates these components. bwboundaries returns B, a P-by-1 cell array, where P is the number of objects and holes. Each cell in the cell array contains a Q-by-2 matrix. Witrynaimshow opens a regular graphics device, meaning that it is possible to overlay lines and points over the image, like with any regular plot. The bottom left corner of the image is …
Witrynaimshow (BW) displays the binary image BW in a figure. For binary images, imshow displays pixels with the value 0 (zero) as black and 1 as white. example imshow (X,map) displays the indexed image X with the colormap map. example imshow (filename) displays the image stored in the graphics file specified by filename.
Witrynaimshow (BW) displays the binary image BW. Values of 0 display as black, and values of 1 display as white. imshow (X,map) displays the indexed image X with the colormap map. imshow (RGB) displays the truecolor image RGB.
