Visualization of in-vitro Blood Vessels in Contrast Images Based on Discrete Wavelet Transform Decomposition

This repository has the functions to implement the methods described in the conference article: "Visualization of in-vitro Blood Vessels in Contrast Images Based on Discrete Wavelet Transform Decomposition", developed as part of the project "Visualization and localization of blood vessels" at INAOE.

Abstract

Visualization of blood vessels in speckle 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.

Contents

• f_i2mtc2019.m - Matlab script. The script f_i2mtc2019.m contains 1 main function (f_i2mtc2019) and four auxiliary functions (f_sk, f_denoising, f_binarize, f_mapping) to implement the methods described in this paper.

• data.mat - MAT file. It contains an in-vitro speckle image of a bifurcated blood vessel at a depth of 300 µm. The image is stored as a variable with the name 'img' and is an array of 288x280 pixels in grayscale.

• demo.mlx - Matlab live script. It contains an example of the image processing available in data.mat. This live script describes step by step the use of the auxiliary functions described in f_i2mtc2019.m
