compress_to_keypoints

Arguments:

Description:

Compress each of the selected images into a set of keypoints that can be further decompressed using command decompress_from_keypoints.
Beware: This type of compression is effective only for images with very smooth content.
method can be { 0:PDE | 1:RBF }. Add 2 to method to skip the point removal step.
max_keypoints is the maximal number of keypoints generated by the compression method. If max_keypoints<0, the removal step is not done when number of maximal keypoints has been reached. max_keypoints=0 means no limits.
err_avg is the desired average compression error.
err_max is the desired pointwise max compression error.
err_command is the code of a command that inputs the two images [reference] and [compressed] and compute a single error map as a last image.
Defaults values: method=3, max_keypoints=0, err_avg=1%, err_max=5% and err_command=-. [0] norm.
