Analysis of neurite directionality
Plišková, Diana ; Čmiel, Vratislav (oponent) ; Odstrčilík, Jan (vedoucí práce)
The thesis is focused on the design of a suitable method for analyzing the directionality of neurites. Fluorescence microscopy images of neurons were used. Prior to segmentation, the images had to be preprocessed, using contrast adjustment, sharpening, and adaptive filtering using a Weiner filter.The individual proposals of segmentation methods consisted of simple thresholding, area growth and the use of morphological operations. Subsequent directionality analysis used the direction of the gradients in the image. The proposed method was also used as a classifier, which was able to segregate the respective images into classes according to the direction of the growth.
