NettetThe HOG descriptor has some key advantages. Since it operates on localized cells, the method maintains the invariance to geometric and photometric transformations. We implemented the HOG descriptor on C/C++ and using OpenCV [9] libraries following four steps as shown below: 2012 24th International Conference on Microelectronics (ICM) Nettet1. mar. 2024 · The new method allows a more efficient implementation of HOG in general, and particularly in field-programmable gate arrays (FPGAs), by considerably reducing the area (thus increasing the level... aratuan

Nettet10. des. 2024 · HOG is a feature descriptor to extract features related to the direction and orientation of edges from image data. In general, it is a simplified representation of the image that contains only the most important information, such as the number of occurrences of gradient orientation in localized portions of an image.
