languages like python, with libraries such as opencv and scikit-image, are popular for implementing find edges. additionally, languages like c++ and java have libraries and frameworks that support image processing and edge detection. the choice of language often depends on the specific project ...
Foroutput0I guess the 2184 are the points representing the contours of every segmented object. I don't understand where the 116 comes from. The yolov8n-seg.pt says it segments 80 classes since it's trained with COCO datset, then why the 116?
Feature detection: A domain expert detects salient and distinctive objects (closed boundary areas, edges, contours, line intersections, corners, etc.) in both the reference and sensed images. Feature matching: It establishes the correlation between the features in the reference and sensed images. The...
