A new parallel thinning algorithm for gray scale images
نویسندگان
چکیده
In this paper we introduce a parallel algorithm for thinning gray scale images. The algorithm is based on repeatedly conditionally eroding the gray level objects in the image until a one pixel thick pattern is obtained along the center of the high intensity region. Erosion conditions are devised to assure preserving connectivity. To properly handle objects with hollows, gray level gradient is used in the preprocessing phase to detect significant hollows. This allows processing of realistic nontrivial gray level objects. Results of applying the algorithm on a variety of images will be shown.

A New Algorithm for Skin Lesion Border Detection in Dermoscopy Images
Background: With advances in medical imaging systems, digital dermoscopy has become one of the major imaging modalities in the analysis of skin lesions. Thus, automated segmentation or border detection has a great impact on the subsequent steps of skin cancer computer-aided diagnosis using demoscopy images. Since dermoscopy images suffer from artifacts such as shading and hair, there is a need ...
متن کاملEvaluation of gray scale changes of CBCT system images in different axis using the DICOM file
The images of dental CBCT imaging systems used in conic shaped beams, stored in the DICOM format, have various applications in the dentistry, including bone density estimation to select the location of the orthodontic implant, bone loss detection and etc. In these systems, unlike CT imaging systems, the resulting images exhibit gray-scale non-uniformity in each of the different axis in FOV. Thi...
متن کاملA Novel Color Image Compression Method Using Eigenimages
Since the birth of multi–spectral imaging techniques, there has been a tendency to consider and process this new type of data as a set of parallel gray–scale images, instead of an ensemble of an n–D realization. Although, even now, some researchers make the same assumption, it is proved that using vector geometries leads to better results. In this paper, first a method is prop...

Introduction The diagnosis and separation of cancerous tumors in medical images require accuracy, experience, and time, and it has always posed itself as a major challenge to the radiologists and physicians. Materials and Methods We Received 290 medical images composed of 120 mammographic images, LJPEG format, scanned in gray-scale with 50 microns size, 110 MRI images including of T1-Wighted, T...
متن کاملSOME COMMENTS ON THINNING ALGORITHMS FOR 3 - D IMAGESFrancisco Nivando Bezerra
The problem of deening simple points in a two-dimensional binary image was extensively discussed in the literature. This deenition is more complicated for 3-d images due to the introduction of a new topological component, namely, the tunnel. Recently, some simple-point characterizations for these images have been proposed. In this paper we show the equivalences between these new characterizatio...
