摘要

对比图像中血管的可视化是一项重要的任务，因为它用于分析血流动力学和生物组织的健康状况。然而，由于图像中的噪声，主要是在高深度时，这一任务变得困难。本文提出了一种基于离散小波变换的体外血管可视化方法。它还解决了通过形态学操作在提高对比度图像感兴趣的区域分割。结果表明，即使在表皮假体下方700 μ m处，也可以看到血管。

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

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.
