Recognition method and system for component images

摘要

A recognition method includes: retrieving a component image from an image source; utilizing SVD (singular value decomposition) to decompose the component image; and utilizing the decomposed component image for image recognition. In an embodiment, the recognition method further includes: utilizing a light compensation method to calculate at least one light compensation coefficient; utilizing the light compensation coefficient to process the component image to obtain a light-compensated component image; and utilizing the light-compensated component image for image recognition.

1. A recognition method comprising:
retrieving at least one image of an electronic component from an image source, with the at least one image having pixel values of color channels; searching at least one difference among the color channels of the at least one image; utilizing a singular value decomposition (SVD) method to process the at least one image to obtain a SVD matrix, wherein the SVD matrix is calculated using the at least one difference; applying a color space transformation (CST) method to execute calculation on each color channel, wherein the CST method comprises combining color coefficients by computing a product of the SVD matrix of each of the color channels to obtain a CST image; and projecting the CST image to a high-dimension space for generating correlation and differences of information of the at least one image; and recognizing at least one electronic component from the projected CST image.
