In computer vision, blob detection methods are aimed at detecting regions in a digital image that differ in properties, such as brightness or color, compared to surrounding regions. Informally, a blob is a region of an image in which some properties are constant or approximately constant; all the points … See more One of the first and also most common blob detectors is based on the Laplacian of the Gaussian (LoG). Given an input image $${\displaystyle f(x,y)}$$, this image is convolved by a Gaussian kernel See more A hybrid operator between the Laplacian and the determinant of the Hessian blob detectors has also been proposed, where spatial selection is done by the determinant of the … See more The blob descriptors obtained from these blob detectors with automatic scale selection are invariant to translations, rotations and … See more A natural approach to detect blobs is to associate a bright (dark) blob with each local maximum (minimum) in the intensity landscape. A main problem with such an approach, however, … See more From the fact that the scale space representation $${\displaystyle L(x,y,t)}$$ satisfies the diffusion equation $${\displaystyle \partial _{t}L={\frac {1}{2}}\nabla ^{2}L}$$ See more By considering the scale-normalized determinant of the Hessian, also referred to as the Monge–Ampère operator, $${\displaystyle \det H_{\mathrm {norm} }L=t^{2}\left(L_{xx}L_{yy}-L_{xy}^{2}\right)}$$ where See more The determinant of the Hessian operator has been extended to joint space-time by Willems et al. and Lindeberg, leading to the following scale-normalized differential expression: See more WebFeb 16, 2024 · The Blob Batch operation allows multiple API calls to be embedded into a single HTTP request.
