Embodiment Construction

[0033] In the following description, as a preferred example, a method for stitching multiple images is proposed. It is obvious to those skilled in the art that modifications including additions and / or substitutions can be made without departing from the scope and spirit of the present invention. Specific details may have been omitted in order not to obscure the invention; however, this disclosure has been written to enable one skilled in the art to practice the teachings of the invention without undue experimentation.

[0034] figure 1 A flow chart is shown showing the steps of a method for stitching multiple images according to an embodiment of the present invention. In step 101, features of candidate strips of an image are calculated. In step 102, candidate feature points are calculated. In step 103, a matching block is determined based on the candidate feature points including at least one pixel. In step 104, the matching block is compared with a plurality of search blo...

Abstract

The invention provided a method for splicing a plurality of images together. The method occupies the smallest memory and the lowest CPU utilization rate, has the smallest file input and output, and still has a higher calculation speed and provides good splicing quality at the same time. The method comprises the steps as follows: a characteristic of each candidate strip of an image is calculated by using mathematical manipulation; matching blocks used for calculating deviation amount between adjacent images are selected at the same time; positions of search blocks which have the maximum correlation coefficients with the matching blocks in the adjacent images are calculated, so that the deviation of the candidate strips is determined; and the splicing reliability of the candidate strips is calculated according to the maximum correlation coefficient of each predefined matching block and the weighting function of the characteristic of the matching blocks, and an optimum splicing path is determined according to the splicing reliability.

Description

technical field [0001] The present invention relates generally to the field of digital image processing. More specifically, the present invention relates to the field of digital image stitching. Background technique [0002] In some cases, it is not possible to capture a large field of view scene at once in a single image with a camera. Therefore, multiple images need to be captured and then digitally combined or stitched into a larger image. For example, a camera placed on a stand is moved to capture a sequence of images with a certain amount of overlap between the images. These images are then stitched together to form a large field of view image. A typical example is microscopic scanning of pathology slides. Due to the limited field of view of the objective lens and the requirement for high magnification, a single image is not enough to obtain a complete picture of a pathology section. However, a series of images can be captured and further stitched together to form ...
