Adaptive feature extraction method for capsule endoscopy images

Abstract The traditional feature-extraction method of oriented FAST and rotated BRIEF (ORB) detects image features based on a fixed threshold; however, ORB descriptors do not distinguish features well in capsule endoscopy images.Therefore, a new feature detector that uses a new method for setting thresholds, called the adaptive threshold FAST and F

Analyzing the Saturation of Growing Stem Volume Based on ZY-3 Stereo and Multispectral Images in Planted Coniferous Forest

Recently, remote sensing (RS) technology are becoming an increasingly important technology in estimating forest growing stem volume (GSV), and the saturation issue of spectral variables from various optical sensors severely hinders the improvement of mapping forest GSV, especially in the planted forest with high GSV.Forest canopy height is widely c

Multiscale deformation analysis by Cauchy-Navier wavelets

A geoscientifically relevant wavelet approach is established for the classical (inner) displacement problem corresponding to a regular surface (such as sphere, Wax Melt Burner ellipsoid, and actual earth surface).Basic tools are the limit and jump relations of (linear) elastostatics.Scaling functions and wavelets are formulated within the framework
