Morphological Scale-Space based Vessel Segmentation of Retinal Image

2012 Annual IEEE India Conference (INDICON), 2012
This paper introduces a novel procedure to segment retinal vessels using new technique namely Morphological Angular Scale-Space (MASS). Line structuring element is rotated about the seed point to determine the curvature of the vessels thereby ensuring that the components remains connected along vessels segmented.

Document image segmentation using wavelet scale-space features

IEEE Transactions on Circuits and Systems for Video Technology, 2002
An efficient and computationally fast method for segmenting text and graphics part of document images based on textural cues is presented. We assume that the graphics part have different textural properties than the nongraphics (text) part. The segmentation method uses the notion of multiscale wavelet analysis and statistical pattern recognition.

Segmentation Neural Network Incorporating Scale-Space in the Application of Cardiac MRI

Journal of Medical Imaging and Health Informatics, 2020
In this work, we present an image segmentation algorithm based on the convolutional neural network framework where the scale space theory is incorporated in the course of training procedure. The construction of data augmentation is designed to apply the scale space to the training data in order to effectively deal with the variability of regions of ...

SCALE-SPACE SEGMENT GROWING FOR HIERARCHICAL DETECTION OF BILIARY TREE STRUCTURE

International Journal of Wavelets, Multiresolution and Information Processing, 2005
Liver diseases are a common medical problem, especially amongst the population of developing countries. Magnetic Resonance Cholangio Pancreatography (MRCP) has become the popular non-invasive, non-ionizing examination for analysis of the hepatobiliary structure in the liver.

Robust and accurate image segmentation using deformable templates in scale space

Proceedings of International Symposium on Computer Vision - ISCV, 2002
The paper presents a new image segmentation algorithm using deformable templates in scale space. The deformable templates are grey level patterns with clearly defined image features to represent ideal segmentation results of some generic percepts. To segment a specific target in an image, the algorithm deforms the corresponding generic template to ...

Texture segmentation using local energy in wavelet scale space

1996
Wavelet transforms are attracting increasing interest in computer vision because they provide a mathematical tool for multiscale image analysis. In this paper, we show that i) the subsampled wavelet multiresolution representation is translationally variant; and ii) a wavelet transform of a signal generally confounds the phase component of the analysing

Hierarchical image segmentation using a watershed scale-space tree

7th International Conference on Image Processing and its Applications, 1999
The watershed transformation is a useful morphological segmentation tool which has been used in a variety of grey-scale image processing applications. However, a major problem with the watershed transformation is that it produces a severe over-segmentation due to the great number of minima embedded in the image or its gradient, and therefore it is ...
