Detects keypoints in an image

keypoints = obj.detect_elliptic(img)
[...] = obj.detect_elliptic(..., 'OptionName',optionValue, ...)

Input

• img Image, 8-bit grayscale image.

Output

• keypoints The detected keypoints, 1-by-N structure array.

Options

• Mask optional mask specifying where to look for keypoints. Not set by default.

Detects keypoints in the image using the wrapped detector and performs affine adaptation to augment them with their elliptic regions.
