Proposed Hough Technique for Estimating Climatic Conditions recorded in the Cross Section of Tree Images

Complex ensemble of shapes in an image is very difficult for segmentation. Hough transform is one of the robust algorithms for detecting geometric shapes in the images. The modification of this Hough transform is used for effecting way of segmenting images. By tuning the parameters of the circle detection model, extracting the concentric shapes is achieved. In this paper, we proposed an algorithm for finding the distance between the concentric closed shapes in an image. These achieved by splitting the image into four quadrants and apply the Hough transform for detecting the curves in each quadrant and finally combine the result of four quadrants and achieve the result.
