Abstract
Visualization of blood vessels in contrast images is an important task as it is used to analyze the dynamics of the blood flow and the health status of biological tissue. However, this task becomes difficult due to the noise in the image, mainly at high depths. This work proposes a methodology based on the Discrete Wavelet Transform to improve in-vitro blood vessels visualization. It also addresses the segmentation of the regions of interest through morphological operations in improved contrast images. Results show that it is possible to visualize the blood vessels even at 700$\mu$m below an epidermis phantom.
