Detects keypoints in an image or image set.
keypoints = obj.detect(img)
keypoints = obj.detect(imgs)
[...] = obj.detect(..., 'OptionName',optionValue, ...)
Input
- img Image (first variant), 8-bit grayscale image where
keypoints (corners) are detected.
- imgs Image set (second variant), cell array of images.
Output
- keypoints The detected keypoints. In the first variant,
a 1-by-N structure array. In the second variant of the
method,
keypoints{i} is a set of keypoints detected in
imgs{i}.
Options
- Mask A mask specifying where to look for keypoints
(optional). It must be a logical or 8-bit integer matrix
with non-zero values in the region of interest. In the
second variant, it is a cell-array of masks for each input
image,
masks{i} is a mask for imgs{i}.
Not set by default.
