Bas-relief manual

Look at this squirrel with big ears:

Split the channels RGB like as previous sample. We can't see the good depth. Let's use the other colour mode - Lab (Image->Mode->Lab Color). Look at the channel a. This is good for depth map.

Split channels and save the channel a as a depth map. Don't forget to convert Grayscale into RGB colour mode (Image -> Mode -> RGB colour). Then use Image -> Adjustments -> Auto Contrast. Now make Filter -> Blur -> Blur and Auto Contrast again. Repeat this process.

Open the image and depth map in the program Bas-relief. Set Parallax = 10 and make the anaglyph image. We get a not very well image. Let's use the dialogue Segmentation smoothing to perfect the stereo image. Click button Smooth... to open dialogue Segmentation smoothing.

This dialogue is intended for smoothing of the depth map. A custom algorithm is used here, that doesn't blur the image's outline. In the beginning one needs to create an outline image, setting necessary outline level (Outline image level). Lower values of the outline level mean that lighter outlines will be emphasized:

outline image level = 50outline image level = 20

Click the buttons Smooth depth map. Before you need to set the Smoothing degree. Newly created files have a suffix New in their names.

Smoothing without outline blurring. Smooth level = 50

Click Open depth map to open new depth map instead old. Look at the two anaglyphic images before and after smoothing:
