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 ...

This paper addresses the problem of detecting faint edges in noisy images. Detecting edges is important since edges mark the boundaries of shapes and provide cues to their relief and surface markings. Noisy images are common in a variety of domains in which objects are captured under limited visibility. mass renumbering exitsWebFirst, as our goal is to detect faint edges in possibly very noisy images, the strips considered need to be wide.
