The goal of the proposed work to achieve a high quality image (i.e., one with high contrast, and high resolution) using a concise algorithm and a simple antenna system. One of the simpler algorithms is the confocal approach developed by Xu et. al [4]. This approach avoids complex image reconstruction algorithms by synthetically focusing reflections from the breast. It seeks to identify the presence...
This work aims at selecting useful features in critical angles and distances by Gray Level Co-occurrence Matrix (GLCM). In this project, images were labeled based on physician opinion in two groups (malignant or benign). These labeled images were used in classification analysis. Images were opened and read in Matlab software. The tumors were cropped in rectangular shape manually; then graycomatrix...
Breast cancer is one of the most common cancers among woman of the developing countries in the world, and it has also become a major cause of death. Treatment of breast cancer is effective only if it is detected at an early stage. X-ray mammography is the most effective method for early detection but the mammography images are complex. Thus nowadays, image processing and image analysis techniques...
A technique is proposed for detection of tumor in digital mammography. We here proposed a statistical parameters such as probability and entropy based image segmentation of mammographic images. This algorithm is consists of three stages. First we compute probability of each quantization level of the image and replace every pixel by its probability to generate probability image. On this image we perform...
Breast cancer is a disease that can be treated if detected in its early stages. Microcalcifications are high-frequency components on digital images. A transform that deals with frequency components can be used in trying to detect these objects on the breast image. We used the wavelet transform on the proposed work to detect these elements and to classify the nature of their borders, being smooth or...
Today Breast cancer is the leading cause of death of women. Currently the effective method for early detection and screening of breast cancers is Ultrasonography. But the high rate of false positives in mammography causes a large number of unnecessary biopsies. Ultrasonography is an important adjunct to mammography in breast cancer detection. The accuracy rate of breast ultrasound can reach a high...
