Image change detection algorithms: a systematic survey
TLDR
In this paper, the authors present a systematic survey of the common processing steps and core decision rules in modern change detection algorithms, including significance and hypothesis testing, predictive models, the shading model, and background modeling.Abstract:
Detecting regions of change in multiple images of the same scene taken at different times is of widespread interest due to a large number of applications in diverse disciplines, including remote sensing, surveillance, medical diagnosis and treatment, civil infrastructure, and underwater sensing. This paper presents a systematic survey of the common processing steps and core decision rules in modern change detection algorithms, including significance and hypothesis testing, predictive models, the shading model, and background modeling. We also discuss important preprocessing methods, approaches to enforcing the consistency of the change mask, and principles for evaluating and comparing the performance of change detection algorithms. It is hoped that our classification of algorithms into a relatively small number of categories will provide useful guidance to the algorithm designer.read more

Semi-Supervised Novelty Detection Using SVM Entire Solution Path
TL;DR: This work proposes the use of entire solution path algorithms for the CS-SVM in order to facilitate and accelerate parameter selection for SSND and presents a low-density (LD) criterion for selecting optimal classification boundaries, thus avoiding recourse to cross validation that usually requires information about the “change” class.

SAR Image Change Detection Based on Multiscale Capsule Network
TL;DR: A multiscale capsule network (Ms-CapsNet) to extract the discriminative information between the changed and unchanged pixels and significantly improves the robustness to speckle noise is proposed.

Robust Change Captioning
TL;DR: A novel Dual Dynamic Attention Model (DUDA) to perform robust Change Captioning, which learns to distinguish distractors from semantic changes, localize the changes via Dual Attention over “before” and “after” images, and accurately describe them in natural language via Dynamic Speaker.

Geometric Change Detection in Urban Environments Using Images
TL;DR: The proposed method can be used to significantly optimize the process of updating the 3D model of an urban environment that is changing overtime, by restricting this process to only those areas where changes are detected.

Distinctive Image Features from Scale-Invariant Keypoints
TL;DR: This paper presents a method for extracting distinctive invariant features from images that can be used to perform reliable matching between different views of an object or scene and can robustly identify objects among clutter and occlusion while achieving near real-time performance.

Stochastic Relaxation, Gibbs Distributions, and the Bayesian Restoration of Images
Stuart Geman,Donald Geman +1 more
TL;DR: The analogy between images and statistical mechanics systems is made and the analogous operation under the posterior distribution yields the maximum a posteriori (MAP) estimate of the image given the degraded observations, creating a highly parallel ``relaxation'' algorithm for MAP estimation.
