Bounding box loss
WebOct 17, 2024 · There are 5 terms in the loss functionas shown above. 1st term (x, y): The bounding box x and y coordinates is parametrized to be offsets of a particular grid cell location so they are also bounded between 0 and 1. And the sum of square error (SSE) is estimated only when there is object. WebNov 7, 2016 · The bounding boxes are simply the (x, y) -coordinates of the object in the image. The bounding boxes for the training and testing sets are hand labeled and hence why we call them the “ground-truth”. Your goal is to take the training images + bounding boxes, construct an object detector, and then evaluate its performance on the testing set.
