Abstract:
Abstract: Objective To solve the problem that computer-aided sperm analysis system lacks of objective indicators for evaluating the performance of microscopic image filtering algorithms. Methods The correlation among continuity of sperm trajectory tracking, gray-level histogram of filtering image and performance of filtering algorithm was analyzed and then, the correlation under different noise densities was quantitatively calculated. Finally, a mathematical model of structure preservation factor was established. Results The larger the structure preservation factor of the filtering algorithm was, the higher the continuity level of sperm trajectory tracking was, which proved the effectiveness of the structure preservation factor as a measurement of filtering performance. Conclusion The structure preservation factor overcomes the subjectivity of the performance evaluation of filtering algorithm for microscopic image. The proposed indicator can not only provide theoretical guidance for the selection of filtering algorithm for sperm microscopic image, but also provide quality control basis for computer-aided sperm analysis system from the perspective of computer image processing.
