Embodiment Construction

[0037] Various example embodiments will be described more fully hereinafter with reference to the accompanying drawings, in which some example embodiments are shown. In the drawings, like reference numerals denote like elements throughout. Duplicate descriptions may be omitted.

[0038] figure 1 is a flowchart illustrating a method of matching images according to example embodiments.

[0039] refer to figure 1 , each of the plurality of input images is divided into a plurality of image blocks (S100). Each input image can be evenly partitioned such that multiple image patches can have the same pixel width dimension and pixel height dimension. will be referenced below Figure 6 Describes the partitions and image blocks of the input image.

[0040] A feature point map including a plurality of feature point blocks respectively corresponding to the plurality of image blocks is generated by extracting feature points included in each of the plurality of image blocks (S200). Al...

Abstract

Disclosed are a method of matching images for merging the images and a data processing device performing the same. Each input image from a plurality of input images is divided into a plurality of image tiles. A feature point map including a plurality of feature point tiles respectively corresponding to the plurality of image tiles is generated by extracting feature points included in each image tile of the plurality of image tiles. A descriptor map including a plurality of descriptor tiles respectively corresponding to the plurality of feature point tiles is generated by generating descriptors of feature points included in the feature point map. Mapping information containing matching relationships between feature points included in different input images of the plurality of input images is generated based on a plurality of descriptor maps respectively corresponding to the plurality of input images. Image merging performance may be enhanced by dividing the input image into the plurality of image tiles to increase distribution uniformity of the feature points.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2020-0082313 filed with the Korean Intellectual Property Office (KIPO) on Jul. 3, 2020, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] Example embodiments relate generally to semiconductor integrated circuits, and more particularly, to a method of matching images to be merged and a data processing apparatus performing the method. Background technique [0004] In the field of computer vision, corresponding points between images are used to merge images. The merged images can be applied to various image processing techniques such as image stitching, noise reduction, dynamic range conversion, etc. In order to merge images, the image matching process can obtain the mapping relationship between the feature points in the multiple images to be merged. Such image matching requires extensive processing...
