WebFeb 3, 2024 · SIFT (Scale Invariant Feature Transform) Detector is used in the detection of interest points on an input image. It allows identification of localized features in images which is essential in applications such as: Object Recognition in Images. Path detection and obstacle avoidance algorithms. Gesture recognition, Mosaic generation, etc. WebFeb 21, 2024 · It turned out that my original mask that I created using threshold operations, even though looked binary, was a 3-channel image ( [rows], [cols], 3). Thus it couldn't be accepted as a mask. After checking for type and shape (has to be uint8 and [rows,cols,1]): print (mask.dtype) print (mask.shape) Convert the mask to gray if it's still 3-channel: read\u0027s ice cream
