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 … WebEdge detection is a challenging, important task in image analysis. Various applications require real-time detection of long edges in large and noisy images, possibly under limited computational resources. While standard edge detection methods are computationally fast, they perform well only at low levels of noise. Modern sophisticated methods, in contrast, …
Detecting Curved Edges in Noisy Images in Sublinear …
WebPDF A fundamental question for edge detection is how faint an edge can be and still be detected. In this paper we offer a formalism to study this question and subsequently introduce a hierarchical edge detection algorithm designed to detect faint curved edges in noisy images. In our formalism we view edge detection as a search in a space of … WebMay 25, 2015 · a new, computationally efficient algorithm to detect faint. curved edges of arbitrary shapes and lengths, under low. signal-to-noise ratios (SNRs).
