The present work focus on the identification of malignant neoplasias in breast by using the Hough Transform in digital images. A detector of circumference was implemented based on the Hough Transform once the pattern to identify is circular. The detector presented here was developed using MatLab, and was applied to detect circumferences in tomography images.

We extend the velocity Hough transform (VHT) for tracking objects with arbitrary velocity by ®nding an optimal, smooth trajectory that maximises its associated energy. Optimisation is achieved by temporal dynamic programming (DP). Tracking in noise is much superior to the standard Hough transform (SHT).

INTRODUCTION: Automatic segmentation and classification of brain tumors help in improvement treatment which will increase the life patient. Tumor may be noncancerous (benign) or cancerous (malignant). Precancerous cells also form into cancer.OBJECTIVES: Hough CNN is applied for selected section applies hough casting technique segmentation. METHODS: A multistage methodof extracting features, wit...

Quantization-free parameter space reduction in ellipse detection Kuang Chung Chen Ellipse modeling and detection is an important task in many computer vision and pattern recognition applications. In this thesis, four Hough-based transform algorithms have been carefully selected, studied and analyzed. These techniques include the Standard Hough Transform, Probabilistic Hough Transform, Randomize...

It is important to detect crop rows accurately for field navigation. In order to spray on line, a variable rate spray system should detect the crop center line accurately. Most existing detection algorithms are slow to detect crop rows because of the complicated calculation. The gradient-based Random Hough Transform algorithm could improve the calculation speed and reduce the computation effect...

Randomized Hough Transform (RHT) has been recently proposed as a new and eecient variation of the Hough Transform for curve detection. In this paper the RHT is combined with the Fuzzy Cell Hough Transform (FCHT) and a new variation, the Randomized Fuzzy Cell Hough Transform (RFCHT) is proposed. The p-dimensional parameter space of Hough Transform is split into fuzzy cells with overlapped interv...

A number of image analysis tasks of the heart region have to cope with both the problem of respiration and heart contraction. While the heart contraction status can be estimated based on the ECG, respiration status estimation must be based on the images themselves, unless additional devices for respiration measurements are used. Since diaphragm motion is closely linked to respiration, we descri...
