Title:
MORPHOLOGICAL PROCESSING METHOD OF DIGITAL IMAGE AND DIGITAL IMAGE PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/053710
Kind Code:
A1
Abstract:
Provided are a morphological processing method of a digital image and a digital image processing device. The morphological processing method of the digital image comprises: determining whether a to-be-detected pixel point in the digital image is a boundary point; if the to-be-detected pixel point is a boundary point, determining whether the to-be-detected pixel point is a directional dilation point; and if the to-be-detected pixel point is the directional dilation point, assigning pixel values of the pixel points in a first pixel point set in the digital image as a first pixel value, according to a position of the to-be-detected pixel point and a first directional dilation matrix. With the method, the digital image can be morphologically processed easily and quickly.
