Multi-feature driven active contour segmentation model for infrared image with intensity inhomogeneity

no code implementations25 Nov 2020 Qinyan Huang, Weiwen Zhou, Minjie Wan, Xin Chen, Qian Chen, Guohua Gu

Active contour model (ACM) is one of the most widely used image segmentation tools at present, but the existing methods only utilize the local or global single feature information of image to minimize the energy function, which is easy to cause false segmentations in IR images.

Adaptive compressed 3D imaging based on wavelet trees and Hadamard multiplexing with a single photon counting detector

no code implementations15 Sep 2017 Huidong Dai, Weiji He, Guohua Gu, Ling Ye, Tianyi Mao, Qian Chen

The proposed multi-resolution photon counting 3D imaging technique acquires a high-resolution 3D image from a coarse image and edges at successfully finer resolution sampled by Hadamard multiplexing along the wavelet trees.
