Detecting faint curved edges in noisy images
WebMay 25, 2015 · Detecting edges is a fundamental problem in computer vision with many applications, some involving very noisy images. While most edge detection methods are fast, they perform well only on relatively clean images. Indeed, edges in such images can be reliably detected using only local filters. Detecting faint edges under high levels of … WebA fundamental question for edge detection in noisy images is how faint can an edge be and still be detected. In this paper we offer a formalism to study this question and …

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 … WebFirst, as our goal is to detect faint edges in possibly very noisy images, the strips considered need to be wide. In such wide strips, the curved edges cannot be well …
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 ... WebDec 20, 2024 · I need to detect that the curvy anomaly exist or not exist and how heavy are they.
