Spermatozoa detection, counting and tracking in video streams to detect asthenozoospermia

Abstract

A semen analysis evaluates certain characteristics of a male's semen and the sperm contained in the semen. The chance of pregnancy will be reduced, if more than 50 percent of a man's sperm lack movement. Assessing the ability of sperm to move forward through the cervix into the fallopian tubes is a widely used measure of male infertility. Since the examination is done by a person through a microscope, a fairly simple system is used for classifying the spermatozoa. This paper proposes a technique to evaluate the motility of human spermatozoon which includes moving object detection, tracking and behavioral analysis. The objective is to measure the speed and quality of movement by tracking video clips of individual sperm cells. The approach chosen was frame differencing on consecutive frames, which identifies moving objects from the portion of a video frame that differs significantly from the previous frame. This method has less computation complexity, high recognition rate and a faster processing speed.

Comparison and implementation of motion detection methods for sperm detection and tracking

“…So that, GMMHF will produce more compound blob as an object and not a spared blob. The experiment will compare 6 (six) motion detection methods such as: GMMHF [10], Frame Difference that used in [8], GMM by C. Stauffer and W. Eric L. Grimson [13], C. Wren et al, [14], and Pixel-Based Adaptive Segmenter by M. Hofmann et al, [15].…”

“…So that, the original shape of head sperm will be changed. In [8] frame difference was used for object detection. In background subtraction methods, frame differencing is a simple method and low computational needs.…”

Spermiogram Görüntülerinden Hareket Belirleme Yöntemleri ile Aktif Sperm Sayısının Tahmini

“…Ancak sperm kalitesini belirleyen sperm hareketliliği, tek bir çerçeve kullanılarak belirlenemez. Son bölütleme grubu için [8][9][10][11][12] çalışmalar iyi örnek olabilir. Li ve ark., Abbiramy ve ark.…”

“…Li ve ark., Abbiramy ve ark. ve Nurhadiyatna ve ark., semende hareket tespit edilerek canlı spermlerin saptanması önerilmektedir [8][9][10]. Arkaplan belirleme için Gauss Karışım Modeli (GKM) kullanılır.…”

New hybrid approach for identification of spermatozoa in human semen sample using microscope image processing techniques

“…Features of identified objects was stored and labeled them accordingly. Identified spermatozoa were tracked in each frame [9]. The review on techniques of CASA for semen analysis indicates that Pathologist and microbiologist need a manual cum standard computer assisted, cost effective semen analyzer with optimal result, since semen analysis is now routine checkup for infertile couples.…”
