Benefits of technology

This technology helps improve health by providing an effective way for people who are sick or have issues with their body's ability to absorb nutrients from food sources like fava beans.

Problems solved by technology

This patented technical problem addressed in the patents relates to identating similar photos captured together due to their location within one site versus another site. Current methods rely heavily upon extracting specific parts of these photo-images like key frames or backgrounds, which can lead to overlapped areas between them. Additionally, current techniques use global featurities instead of individual ones, resulting in incorrect matchings even after multiple repetitive steps.

Abstract

An embodiment of the invention provides a method for searching matched pictures and a method and a device for searching pictures. By setting the first proportion threshold value and the second proportion threshold value, the first portion threshold value is larger than the second threshold value, the larger matching threshold value is used for matching of local characteristics, on this basis, pictures with matching proportion smaller than the first proportion threshold value and larger than the second proportion threshold value are screened by a perceptual hashing matching manner, pictures with Hamming distance smaller than the preset first distance threshold value are contained in picture matching results, on one hand, matching accuracy of the pictures is guaranteed by the aid of the larger matching threshold value, on the other hand, for pictures with matching superposition proportion of the local characteristics between the larger matching threshold value and the smaller matching threshold value, and the pictures can be screened in the perceptual hashing matching manner. On the premise of accuracy of the screened pictures, the number of the pictures in the searching results is increased.
