Embodiment Construction

[0041] The present invention will be further elaborated below in conjunction with the accompanying drawings.

[0042] like figure 1 As shown, a method for recognizing jigsaw puzzles based on outlines and colors includes the following steps: S1, obtaining a color image of a jigsaw puzzle through a camera; S2, preprocessing the color image in step S1; S3, performing a preprocessing on the color image in step S1 Contour detection; S4, performing color detection on the contour information in step S3; S5, shape recognition.

[0043] S2. Preprocessing the color image in step S1 specifically includes the following steps: S21. Performing light preprocessing on the input color image, usually using a white balance method to prepare for subsequent color recognition; S22. Performing light preprocessing on the color image. Grayscale transformation to obtain a grayscale image; S23, performing noise reduction processing on the grayscale image obtained in step S22 using median filtering to r...

Abstract

The invention discloses a seven-piece puzzle identification method based on contours and colors. The seven-piece puzzle identification method comprises the following steps: S1, obtaining the color image of a seven-piece puzzle through a camera; S2, preprocessing the color image in the step S1; S3, carrying out contour detection on the color image in the step S1; S4, carrying out color detection on contour information in the step S3; S5, carrying out shape identification. The seven-piece puzzle identification method has the beneficial effects that the method is suitable for any electronic equipment and platforms, such as human-computer interaction, and a physical toy in traditional games and electronic equipment are skillfully combined together through an advanced computer algorithm, so that a game of combining the real world with a virtual technology together is realized, and the limitation problem for seven-piece puzzle game when an embedded platform is low in processing speed and limited in memory resources is effectively solved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a jigsaw puzzle recognition method based on contours and colors. Background technique [0002] Contour detection has a wide range of applications in virtual reality, self-controlled vehicles, robot environment analysis, object tracking and recognition in monitoring systems, biomedical image processing, industrial online automatic detection, shape inversion, etc. Contour detection technology is to use the difference between the object and the background in terms of grayscale, color or texture features of the image to find a closed contour to segment the most prominent object from the background. There are two criteria for defining contours: natural contours have smooth shapes, and contours divide an image into distinct regions. At present, our commonly used classic contour detection method is to construct a differential operator that is sensitive to the step change of pi...
