Detecting faint curved edges in noisy images
WebThis paper considers the problem of detecting faint edges in noisy images. Our key contribution is the introduction of a new, computationally efficient algorithm to detect faint curved edges of arbitrary shapes and lengths, under low signal-to-noise ratios (SNRs). A key feature of our algo-rithm is that the longer an edge is, the fainter it ... WebApr 14, 2024 · The noise in a space surveillance platform mainly includes thermal noise, shot noise, dark current noise, and stray light noise, which could affect the accuracy of space debris saliency detection. The first three noises are caused by the statistical nature of photodetection or photodiode in sensor systems [ 61 ], which can be represented as …
