The function IMOVERLAY creates a mask-based image overlay. It takes input image and a binary mask, and it produces an output image whose masked pixels have been replaced by a specified color.
NOTE: This original implementation of IMOVERLAY was superseded in R2016a by a new function, with the same name, in the Image Processing Toolbox. The version here has been renamed to IMOVERLAY_OLD.

| 版本 | 已发布 | 发行说明 | Action |
|---|---|---|---|
| 1.3 | Renamed to IMOVERLAY_OLD. Use the new version (R2016a) in the Image Processing Toolbox. |
||
| 1.2.0.1 | Updated license |
||
| 1.2.0.0 | Based on a suggestion from Lasse, I added code to automatically convert the mask input to be logical. |
||
| 1.0.0.0 | Based on a suggestion by Matt Whitaker, I added documentation and an example explaining how to use mat2gray for double / single grayscale images outside the normal [0, 1] range. |
