143 papers with code • 8 benchmarks • 9 datasets Edge Detection is a fundamental image processing technique which involves computing an image gradient to quantify the magnitude and direction of edges in an image. Image gradients are used in various downstream tasks in computer vision such ...
Edge detection has long been an important problem in the field of computer vision. Previous works have explored category-agnostic or category-aware edge detection. In this paper, we explore edge detection in the context of object instances. Although object boundaries could be easily derived from ...

By default, we use Canny edge detector to extract edge information from the input images. If you want to train the model with an external edge detection (Holistically-Nested Edge Detectionfor example), you need to generate edge maps for the entire training/test sets as a pre-processing and ...
Edge detection algorithms find boundaries between areas with different colors or intensities Image feature detection reduces a big, messy image into a more compact representation of the visual structures that are present within it. This can potentially make life easier for any AI algorithms that are ...

In this study, we tackle the challenging fine-grained edge detection task, which refers to predicting specific edges caused by reflectance, illumination, normal, and depth changes, respectively. Prior methods exploit multi-scale convolutional networks, which are limited in three aspects: (1) Convoluti...
