AI Technical Summary

Problems solved by technology

ASIC designed circuits have very poor flexibility and scalability
The reconfigurable computing array has low efficiency and slow speed when performing image processing, and it is difficult to process large-resolution image signals in real time; and this structure is complicated to control, which is not conducive to widespread use
[0004] It can be seen that the current technology cannot meet the requirements of performance and flexibility when processing large-resolution grayscale images.

The reconfigurable gray-scale morphological image processor is further established on the basis of the structure; an implementation method of gray-scale morphological operation by use of the processor is provided. The reconfigurable gray-scale morphological image processor is capable of realizing a plurality of gray-scale morphological operations flexibly, simple and regular in structure, high in processing speed, and capable of performing real-time processing on high-resolution gray-scale images.

Description

technical field [0001] The invention relates to the technical field of grayscale image processing, in particular to a reconfigurable grayscale morphological image processor for grayscale image processing, a grayscale operation unit thereof, and a method for realizing morphological operation. Background technique [0002] Grayscale morphological operations are widely used in image processing and analysis, computer vision, pattern recognition, video segmentation and other fields. The image processing algorithm method based on gray-scale morphological operation is simple, easy to implement, and has a fast calculation speed, which is very suitable for the use of embedded systems. [0003] Currently, there are mainly two types of embedded hardware systems for gray-scale morphological operations: ASIC and reconfigurable operation arrays. Both types of circuits have their inevitable flaws. The circuit designed by ASIC has very poor flexibility and scalability. The reconfigurable...
