Find Blobs
Find Blobs is useful in finding all groups of connected pixels, or blobs, in an Image. This node expects a CV input.
Input pins
Input: incoming CV Mat with 1, 3, or 4 channels,
Filter by threshold: enforces a Threshold value on the input which is between the Min threshold and Max threshold values.
Filter by area: filters the Output, so that the detected blobs are between the Min area and Max area.
Min distance: the minimum distance between Blobs. If the distance between two blobs is smaller than the chosen value, then those two separate blobs will be combined into one.
Max track count: maximum amount of Blobs in Output.
Output pins
Relative X, Y, area: relative coordinates of the blobs formatted as such: x position/image width, y position/image height, area = area of blob/area image.
