Abstract

A method for an attention-driven image segmentation by using at least one adaptive loss weight map is provided to be used for updating HD maps required to satisfy level 4 of autonomous vehicles. By the method, vague objects such as lanes and road markers at distance may be detected more accurately. Also, the method can be usefully performed in military, where identification of friend or foe is important, by distinguishing aircraft marks or military uniforms at distance. The method includes steps of: a learning device instructing a softmax layer to generate softmax scores; instructing a loss weight layer to generate loss weight values by applying loss weight operations to predicted error values generated therefrom; and instructing a softmax loss layer to generate adjusted softmax loss values by referring to initial softmax loss values, generated by referring to the softmax scores and their corresponding GTs, and the loss weight values.

Description

technical field [0001] This application relates to a method for Attention-Driven image segmentation by using at least one Adaptive loss weighted map to update the High Definition (HD) map to meet the level of self-driving cars 4 requirements. More specifically, a method for image segmentation by using at least one adaptive loss weighted map, a learning device, a testing method and a testing device using the method and the learning device (LEARNING METHOD ANDLEARNING DEVICE FOR ATTENTION-DRIVEN IMAGE SEGMENTATION BY USING AT LEAST ONE ADAPTIVE LOSS WEIGHT MAP TO BE USED FOR UPDATING HD MAPS REQUIRED TO SATISFYLEVEL 4 OF AUTONOMOUS VEHICLES AND TESTING METHOD AND TESTING DEVICE USING THE SAME). Wherein, described method comprises the following steps: [0002] Step (a), when at least one input image is obtained, (i) instruct the encoding (Encoding) layer of CNN to generate at least one feature map by performing more than one convolution operation on the input image, and (ii) in...
