LEARNING METHOD AND LEARNING DEVICE FOR IMAGE SEGMENTATION, AND IMAGE SEGMENTATION METHOD AND IMAGE SEGMENTATION DEVICE USING THE SAME

摘要

To provide a learning environment for preventing loss from becoming small in a backpropagation process in a learning process for image segmentation.SOLUTION: (2-K)-th to (2-1)-th filters perform calculation to reduce feature channels by performing deconvolution on an image input in an opposite direction to a convolution calculation direction of (1-1)-th to (1-K)-th filters, and reducing channels while sequentially increasing the size of a feature map. A decoding layer eventually generates a label image by performing a function, while maintaining the edge of an image obtained in an encoding layer, to destroy a remaining part.SELECTED DRAWING: Figure 2A
