Object-based loss function in segmented neural networks

Abstract

This paper proposes Object-based Loss Function in Segmented Neural Networks. Traditional Segmented Neural Network(SNN) are based on Pixel-based Back Propagation(PBP). Since the pixel ratios of the images occupied by different sizes of objects are not the same, the weight of the small objects in the segmentation is small, which means using PBP may greatly affects the accuracy of the detection when there are a large number of small objects. Considering this defect of PBP, we propose a Object-based Back Propagation(OBP) loss function weight design, that is, the back propagation weights of different objects are not equal, which is inversely proportional to the area occupied by the object. Segmented Neural Networks data set test.
