Multi-sensor slope change detection
We develop a mixture procedure for multi-sensor systems to monitor data streams for a change-point that causes a gradual degradation to a subset of the streams. Observations are assumed to be initially normal random variables with known constant means and variances. After the change-point, observations in the subset will have increasing or decreasing means. The subset and the rate-of-changes ar...
متن کاملFully Distributed Multi-sensor Change-point Detection
Change-point detection has been a fundamental problem in quality control, hazards monitoring and cybersecurity. With the ever-growing complexity of system and enlarging number of sensors, multi-sensor detection algorithms are in real demand. However, most existing detection algorithms consider a centralized approach, meaning that one collects all data at one location, which sometimes may be inf...
متن کاملMulti sensor data fusion for change detection
When performing post-classification comparison using images of different sensors, change detection is still possible even if images have different resolutions. However, in this case, change pixels are detected in the pixel size of coarser resolution image. This problem can be solved using higher resolution aerial photographs or panchromatic images if available. In multi sensor image fusion, ima...
متن کاملMulti-Sensor Sequential Change Detection with Unknown Change Propagation Dynamics
The problem of detecting changes with multiple sensors has received significant attention in the literature. In many practical applications such as critical infrastructure monitoring and modeling of disease spread, a useful change propagation model is one where change eventually happens at all sensors, but where not all sensors witness change at the same time instant. While prior work considere...
متن کاملAnalyzing Multi-sensor Data Fusion Techniques: a Multi-temporal Change Detection Approach
An inevitable tradeoff between spectral and spatial resolution exists in remote sensing systems and it is essential to integrate information from systems with complementary characteristics to improve data interpretability. Panchromatic (PAN) sharpening is a data fusion technique that merges a high spatial resolution PAN image with lower spatial resolution multispectral images. The resulting mer...
