Influences of the feature extraction area of duck egg image for the identification accuracy on the unfertilized duck eggs on the hatching tray

Abstract

AbstractHowever, feature parameter extraction region of duck egg image could affect the identification results of model and the speed of image processing. Therefore, the image skeleton‐maximum inscribed circle algorithm and Hough gradient algorithm (2‐1HT) were proposed to segment duck egg image feature paramer region. Support vector machine (SVM) and naive bayes (NB) models were established to evaluate accuracy of feature parameters extracted by different algorithms. The comparison shows that the SVM model based on feature parameters extracted by image skeleton maximum inscribed circle algorithm has the best discriminant performance, with the value of Q, SE, and SP being 98.81%, 98.44%, and 100.00%, respectively. Moreover, the process speed and prediction accuracy of image skeleton‐maximum inscribed circle algorithm were much higher than that of Hough gradient algorithm.Practical ApplicationsTherefore, optimizing the image feature parameter extraction algorithm of a single duck egg in grouped duck eggs was of great significance to improve the discrimination accuracy of the model and realize the automatic recognition of infertile duck eggs.
