Perceptual Constancy

Perceptual Constancy

Perceptual constancy is the ability to recognize that objects remain consistent and unchanged even when their appearance varies due to changes in sensory input. There are four main types of perceptual constancy: size constancy, shape constancy, color constancy, and brightness constancy.
Size constancy is the recognition that an object remains the same size, even when its image on the retina changes. For instance, a bus is perceived to be large enough to carry people, even if it looks tiny from...

Depth Perception and Spatial Vision

Depth Perception and Spatial Vision

Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

Area of Science:

Remote Sensing
Computer Vision
Machine Learning

Background:

Multi-temporal hyperspectral imagery (HSI) is valuable for change detection (CD) due to rich spectral and spatial data.
Unsupervised domain adaptation (UDA) for HSI-CD faces challenges with limited annotated data and cross-domain distribution discrepancies.
Existing UDA methods struggle with the labor-intensive data annotation and suboptimal transfer performance.

Purpose of the Study:

To address data scarcity and performance limitations in unsupervised domain adaptation for hyperspectral image change detection.
To develop a novel framework, Temporal Self-Construction Cross-Domain learning (TSCCD), for enhanced HSI-CD.
To improve the efficiency and accuracy of transferring CD knowledge across different HSI domains.

Main Methods:

Proposed the Temporal Self-Construction Cross-Domain learning (TSCCD) framework for UDA-based HSI-CD.
Introduced a temporal self-construction mechanism to synthesize bi-temporal source-domain data and perform data-level alignment.
Developed a reweighted amplitude maximum mean discrepancy (MMD) for feature-level domain adaptation and employed an attention-based Kolmogorov-Arnold network (KAN) with high-frequency feature augmentation.

Main Results:

TSCCD framework effectively synthesizes bi-temporal source-domain data from existing HSI classification datasets.
Reweighted amplitude MMD metric significantly enhances feature-level domain adaptation.
The attention-based KAN architecture successfully captures complex change characteristics in HSI data.
Comprehensive experiments on three benchmark datasets show TSCCD outperforms state-of-the-art methods.

Conclusions:

The TSCCD framework offers a robust solution for unsupervised domain adaptation in hyperspectral image change detection.
The proposed methods effectively overcome limitations of data scarcity and cross-domain discrepancies.
TSCCD demonstrates superior performance, paving the way for more practical HSI-CD applications.
