RESUMO

Image processing techniques have been widely used on the analysis and monitoring of several phenomena In farming it contributed with the process of animal reproduction aiming to eliminate human subjectivity when interpreting results in quality analysis of samples In the field of ruminants reproduction among others supervised attributes it was analyzed the whirl formed by the spermatozoon s massal movement This work aims to present alternatives for analyzing Ovis aries semen images available from optical microscopy using techniques such as inertial moment image segmentation and vortex The techniques were evaluated through an Ovis aries film of semen which was collected during its life time The inertial moment technique was able to follow the semen s activity levels through time It was even possible to observe all the changes in the sample produced by temperature adjustment The image segmentation technique enabled the separation of semen in miscellaneous grey levels offering the analyst more information for quality analysis The vortex movement present in semen were monitored following the kinetic displacement of the semen s islands in their vorticity behavior adding more information to the analysis
