Object detection | Overview
bounding box ground truth 4 number to decide a bounding box $$ (x_{left-up}, y_{left-up},x_{right-down}, y_{right-down})\ (x_{left-up}, y_{left-up},width, height) $$ for drawing, another kind $$ (x_{center}, y_{center}, width, height) $$ Dataset every row represent a object File_name, object_class, bounding box(4 value) COCO dataset 80 object class, 330K picture, 1.5M objects anchor box A lot of anchor-box-based algorithm. a series of predictive box. predict whether every anchor box has interested object if yes, predict the offset between anchor box and bounding box Every anchor box is a training sample....
