Fitting parabolas in noisy images
نویسندگان
چکیده
A novel approach to fitting parabolas to scattered data is introduced by putting special emphasis on the robustness of the approach. The robust fit is achieved by not taking into account a proportion α of the “most outlying” observations, allowing the procedure to trim them off. The most outlying observations are self-determined by the data. Procrustes analysis techniques and a particular type of “concentration” steps are the keystone of the proposed methodology. An application to a retinographic study is also presented.

Background Segmentation in Microscopy Images
In many applications it is necessary to segment the foreground of an image from the background. However images from microscope slides illuminated using transmitted light have uneven background light levels. The non-uniform illumination makes segmentation difficult. We propose to fit a set of parabolas in order to segment the image into background and foreground. Parabolas are fitted separately ...
متن کاملNoisy images edge detection: Ant colony optimization algorithm
The edges of an image define the image boundary. When the image is noisy, it does not become easy to identify the edges. Therefore, a method requests to be developed that can identify edges clearly in a noisy image. Many methods have been proposed earlier using filters, transforms and wavelets with Ant colony optimization (ACO) that detect edges. We here used ACO for edge detection of noisy ima...
متن کاملA Convolutional Neural Network based on Adaptive Pooling for Classification of Noisy Images
Convolutional neural network is one of the effective methods for classifying images that performs learning using convolutional, pooling and fully-connected layers. All kinds of noise disrupt the operation of this network. Noise images reduce classification accuracy and increase convolutional neural network training time. Noise is an unwanted signal that destroys the original signal. Noise chang...
متن کاملWell fitting curve models with few parameters for vascular systems on retinal images
Diabetic retinopathy is one of the most common causes of blindness. Thus, a growing demand on automatic screening has risen. Among the anatomical parts, thick vessels can be observed most reliably in fundus images. Especially, the localization of the temporal arcade is highly important to detect other anatomical parts. State-of-art detectors locate the arcade by fitting semi-ellipses or parabol...
متن کاملThree Dimensional Boundary Detection Using Higher-Order Surface Fitting and Directional Smoothing
The authors propose an algorithm for detection of three-dimensional bundaries in noisy images based on higher-order polynomial surface fitting and directional smoothing. Fitting a polynomial to the local intensities gives the intensity hypersurface. An isointensity surface i s derived from the hyperplane and directional smwthiag is defined as smoothing along this isointensjty surface. The devel...
