Locally adaptive tree-based thresholding using the treethresh package in R
Suppose we have, after possible rescaling to obtain unit variance, observed a sequence X = (Xi)i∈I satisfying Xi = μi + i, for i ∈ I, where μ = (μi)i∈I is a possibly sparse signal (i.e. some/most of the μi are believed to be zero), the i are independentN(0, 1) noise, and I is a possibly multidimensional index domain. Being a generalisation of the EbayesThresh method, the TreeThresh method is ba...
متن کاملAdaptive Thresholding in Marine RADARs
In order to detect targets upon sea surface or near it, marine radars should be capable of distinguishing signals of target reflections from the sea clutter. Our proposed method in this paper relates to detection of dissimilar marine targets in an inhomogeneous environment with clutter and non-stationary noises, and is based on adaptive thresholding determination methods. The variance and t...
متن کاملAutomatic Locally Adaptive Smoothing for Tree-Based Set Estimation
Tree-based methods similar to CART have recently been utilized for problems where the main goal is to estimate some set of interest. It is often the case that the boundary of the true set is smooth in some sense, however tree-based estimates will not be smooth, as they will be a union of ‘boxes’. We propose a general methodology for smoothing such sets that allows for varying levels of smoothne...
متن کاملLocally adaptive block thresholding method with continuity constraint
We present an algorithm that enables one to perform locally adaptive block thresholding, while maintaining image continuity. Images are divided into sub-images based some standard image attributes and thresholding technique is employed over the sub-images. The present algorithm makes use of the thresholds of neighboring sub-images to calculate a range of values. The image continuity is taken ca...
متن کاملAutomatic target segmentation by locally adaptive image thresholding
A locally adaptive thresholding algorithm, concerning the extraction of targets from a given field of background, is proposed. Conventional histogram-based or global-type methods are deficient in detecting small targets of possibly low contrast as well. The present research is notable for solving the mentioned problems by introducing (1) shape connectivity measure based on co-occurrence statist...
