- W2942854603 abstract "Human embryos evaluation is one of the most important challenges in vitro fertilization (IVF) programs. The morphokinetic and the morphology parameters of the early cleaving embryo are of critical clinical importance. This stage spans the first 48 h post-fertilization, in which the embryo is dividing in smaller blastomeres at specific time-points. The morphology, in combination with the symmetry of the blastomeres, seem to be powerful features with strong prognostic value for embryo evaluation. To date, the identification of these features is based on human inspection in timed intervals, at best using camera systems that simply work as surveillance systems without any precise alerting and decision support mechanisms. This paper aims to develop a computer vision technique to automatically detect and identify the most suitable cleaving embryos (preferably at Day 2 post-fertilization) for embryo transfer (ET) during treatments. To this end, texture and geometrical features were used to localize and analyze the whole cleaving embryo in 2D grayscale images captured during in-vitro embryo formation. Because of the ellipsoidal nature of blastomeres, the contour of each blastomere is modeled with an optimal fitting ellipse and the mean eccentricity of all ellipses is computed. The mean eccentricity in combination with the number of blastomeres form the feature space on which the final criterion for the embryo evaluation is based. Experimental results with low quality 2D grayscale images demonstrated the effectiveness of the proposed technique and provided evidence of a novel automated approach for predicting embryo quality." @default.
