Single-Image Crowd Counting via Multi-Column …

Single-Image Crowd Counting via Multi-Column Convolutional Neural NetworkYingying Zhang Desen Zhou Siqin Chen Shenghua Gao Yi MaShanghaitech paper aims to develop a method than can accuratelyestimate the Crowd count from an individual image with ar-bitrary Crowd density and arbitrary perspective. To this end,we have proposed a simple but effective Multi-Column Con-volutional Neural Network (MCNN) architecture to map theimage to its Crowd density map. The proposed MCNN al-lows the input image to be of arbitrary size or utilizing filters with receptive fields of different sizes, thefeatures learned by each column CNN are adaptive to varia-tions in people/head size due to perspective effect or imageresolution. Furthermore, the true density map is comput-ed accurately based on geometry-adaptive kernels which donot need knowing the perspective map of the input image.

Fully Convolutional Networks for Semantic Segmentation

Convolutional networks are powerful visual models that yield hierarchies of features. We show that convolu-tional networks by themselves, trained end-to-end, pixels-to-pixels, exceed the state-of-the-art in semantic segmen-tation. Our key insight is to build “fully convolutional” networks that take input of arbitrary size and produce
