Medical Images Inter Frame Motion Analysis via Block Positioning Pixel Subtraction Technique
نویسنده
چکیده
This paper presents a study on image pixels using block positioning pixel subtraction technique to analyse the changes that occur in that region of interest. The changes that happen in the pixels represent the motion translation. Processing a whole video sequence in order to view a certain area of interest will increase the computational and processing time. In order to avoid this situation, the block positioning pixel subtraction technique is applied. The block-based positioning subtraction technique extracts the small block of interest to be processed. This small block of interest is processed individually without the need to process a full frame. This technique divides the frames into small 8 8 macro blocks and identifies the pixels of an area of interest in the small block as motion. Identified motion with changes of pixels value is extracted from the small 8 × 8 macroblock to further analyse the motion changes. Keywords-image pixel; subtraction technique; motion translation; block positioning; 8 × 8 macro-block

Motion compensation in digital subtraction angiography using graphics hardware
An inherent disadvantage of digital subtraction angiography (DSA) is its sensitivity to patient motion which causes artifacts in the subtraction images. These artifacts could often reduce the diagnostic value of this technique. Automated, fast and accurate motion compensation is therefore required. To cope with this requirement, we first examine a method explicitly designed to detect local moti...

The demand to preserve raw image data for further processing has been increased with the hasty growth of digital technology. In medical industry the images are generally in the form of sequences which are much correlated. These images are very important and hence lossless compression Technique is required to reduce the number of bits to store these image sequences and take less time to transmit...

متن کاملMoving Objects Tracking Using Statistical Models
Object detection plays an important role in successfulness of a wide range of applications that involve images as input data. In this paper we have presented a new approach for background modeling by nonconsecutive frames differencing. Direction and velocity of moving objects have been extracted in order to get an appropriate sequence of frames to perform frame subtraction. Stationary parts of ...
