Fluorescence microscopy image classification of 2D HeLa cells based on the CapsNet neural network.

abstract：:This article presents a novel approach of edged and edgeless object-shape recognition and 3D reconstruction from gradient-based analysis of tactile images. We recognize an object's shape by visualizing a surface topology in our mind while grasping the object in our palm and also taking help from our past experience of...
