Adaptive Texture Description and Estimation of the Class Prior Probabilities for Seminal Quality Control

Víctor González-Castro
2014 ELCVIA Electronic Letters on Computer Vision and Image Analysis  
The goal is to develop an automatic system to estimate the proportions of damaged acrosomes and dead spermatozoa using just a computer and a digital camera connected to a phase contrast microscope, which  ...  Contributions Intelligent boar sperm segmentation using thresholding and Watershed A bad segmented sperm head could lead to further errors in description and classification stages.  ...  than classifying intact and damaged acrosomes (indeed, it is still an open problem).  ...

Vitality Assessment of Boar Sperm Using an Adaptive LBP Based on Oriented Deviation [chapter]

Oscar García-Olalla, Enrique Alegre, Laura Fernández-Robles, María Teresa García-Ordás
2013 Lecture Notes in Computer Science  
Concerning the global description of sperm heads, several classical texture algorithms were tested and a descriptor based on Wavelet transform and Haralick feature extraction (WCF13) obtained the best  ...  A new method to describe sperm vitality using a hybrid combination of local and global texture descriptors is proposed in this paper.  ...  The authors would like to thank CENTROTEC for providing us the semen samples and for their collaboration in the acquisition of the images.  ...

Assessment of acrosome state in boar spermatozoa heads using n-contours descriptor and RLVQ

E. Alegre, M. Biehl, N. Petkov, L. Sanchez
2013 Computer Methods and Programs in Biomedicine  
We use gray level images in which spermatozoa have been labelled as acrosome-intact or acrosome damaged using the information of a coupled fluorescent image.  ...  This paper proposes a method for assessing the acrosome state of boar spermatozoa heads using digital image processing.  ...  The authors would like to thank CENTROTEC for providing us the semen samples and for their collaboration in the image acquisition.  ...
