This way, if we want CNN to output k=100 Bounding boxes,cnn the output layer node will be a dimension (k* (4+1) =5*k=500).Training set Construction of 2.1.1 DeepmultiboxHow is the training set structured? The input to the training set is definitely the "Maximum center square crop" on each training image, meaning that the center point of each image is calculated first, Then it is centered from the image to cut out a largest square, in order to meet
