Topological Derivative Applied to Automatic Segmentation of Frontal Breast Thermograms
نویسندگان
چکیده
This paper presents a new method for automatic segmentation of thermographic frontal breast images. First, the method uses a low-pass filter and the topological derivative to get a rough definition of the region of interest (ROI). Then, the previous result is used to initialize the method proposed by Marques. This method uses the adjustment of curves by Quadratic Uniform B-Splines. The efficiency of the proposed method is quantitatively verified using a ground truth developed by a group of experts. Besides, we provide comparisons with a related technique.

Asymmetry Analysis Using Automatic Segmentation and Classification for Breast Cancer Detection in Thermograms
Thermal infrared imaging has shown effective results as a diagnostic tool in breast cancer detection. It can be used as a complementary to traditional mammography. Asymmetry analysis are usually used to help detect abnormalities. However, in infrared imaging, this cannot be done without human interference. This paper proposes an automatic approach to asymmetry analysis in thermograms. It includ...
متن کاملDetecting Breast Cancer from Thermal Infrared Images by Asymmetry Analysis
One of the popular methods for breast cancer detection is to make comparisons between contralateral images. When the images are relatively symmetrical, small asymmetries may indicate a suspicious region. In thermal infrared (IR) imaging, asymmetry analysis normally needs human intervention because of the difficulties in automatic segmentation. In order to provide a more objective diagnostic res...
متن کاملBreast abnormalities segmentation using the wavelet transform coefficients aggregation
Introduction: Breast cancer is the most common cancer among women in the world. The automatic detection of masses in digital mammograms is a challenging task and a major step in the development of breast cancer CAD systems. In this study, we introduce a new method for automatic detection of suspicious mass candidate (SMC) regions in a mammogram. Methods: Mammography is widely used for the early...

متن کاملImage Segmentation Pipeline Based on Level Set and Topological Derivative
In this work we propose a segmentation methodology based on the level set approach for boundary extraction and an optimization method formulated through the topological derivative. First, the methodology uses a low-pass filter and the topological derivative to get a rough definition of the boundaries of interest. Then, morphological operators are applied to fill holes and discard artifacts. Nex...
