This work presents a new approach and an algorithm for binary image representation, which is applied for the fast and efficient computation of moments on binary images. This binary image representation scheme is called image block representation, since it represents the image as a set of nonoverlapping rectangular areas. The main purpose of the image block(More)
Moments constitute a well-known tool in the field of image analysis and pattern recognition, but they suffer from the drawback of high computational cost. Efforts for the reduction of the required computational complexity have been reported, mainly focused on binary images, but recently some approaches for gray images have been also presented. In this(More)
A new nonlinear class of filters, the Coordinate Logic (CL) Filters and their application in edge extraction and enhancement is presented. The CL filters are execute Coordinate Logic Operations (CLOs) among the image points and may be seen as multibinary morphological-like kind of filters. The Image Block Representation (IBR), an advantageous image(More)
This paper describes a binary intage representation schente, called Image Block Representation and presents new algorithms for a number of basic binary image processing and analysis operations, which are rapidly intplemented on block-represented binary images. The main purpose of the hnage Block Representation is to provide an efficient binary image(More)

The main purpose of the Image Block Representation is to provide an efficient binary image representation that permits the execution of operations on(More)
Moments constitute a well known tool in the field of image analysis and pattern recognition but they suffer from the drawback of high computational cost. Efforts for the reduction of the required computational complexity have been reported, but are mainly focused on binary images. Image Block Representation (IBR) has been introduced some years ago and is(More)
In this paper is presented a method for the accurate estimation of the image boundary from incomplete raw MRI data. This is necessary for the phase correction and the image reconstruction from incomplete Cartesian or Radial scans using MR techniques and therefore for the reduction of MRI scan time. The exact estimation method comprises the binarization of(More)
This paper presents an algorithm for the real-time computation of 2-D statistical moments on binary images on the Scan Line Array Processor (SLAP). The binary images are represented as sets of nonoverlapping rectangular areas. This representation scheme is called Image Block Representation. The real-time computation of moments in block represented images is(More)
