Image Processing is a procedure to translate an image into digital figure and carry out some operations to get a better image and take out useful information from it. There are many techniques of digital image processing like image enhancement, compression and reconstruction which are discussed in this paper. Image segmentation is an important method of image processing which is widely used in ...

normal 0 false false false en-us x-none ar-sa digital breast tomosynthesis (dbt) is a technology that creates three dimensional (3d) images of breast tissue. tomosynthesis mammography detects lesions that are not detectable with other imaging systems. if image reconstruction time is in the order of seconds, we can use tomosynthesis systems to perform tomosynthesis-guided interventional procedur...

Digital image is often degraded by many kinds of noise during the process of acquisition and transmission. To make subsequent processing more convenient, it is necessary to decrease the effect of noise. There are many kinds of noises in image, which mainly include salt and pepper noise and Gaussian noise. This paper focuses on median filters to remove the salt and pepper noise. After summarizin...

This paper presents simplified hydrodynamics model for a biomimetic robot fish based on quantitative morphological and kinematic parameters of crangiform fish. The motion of four Pangasius sanitwongsei with different length and swimming speed were recorded by the digital particle image velocimetry (DPIV) and image processing methods and optimal coefficients of the motion equations and appropria...

The process of receiving and analyzing visual information by digital computer is called Digital Image Processing and Scene Analysis. Digital Image Processing is a prevalently evolving field with growing applications in Science and Engineering. Image Processing holds the possibility of developing the ultimate machine that could perform the visual functions of all living beings. Many theoretical ...

Digital cameras are becoming more powerful and affordable with each product generation. This paper describes a new generation digital camera that optimizes image quality and ease of use. Excellent image quality is obtained by employing a megapixel CCD sensor and advanced image processing algorithms. A 1.8” color LCD and a new graphical user interface (GUI) guide the user through the operation o...

Image stitching in 3D film production synchronizes multiple independent frame images as a single high-resolution output. The process is common for displaying large coverage or shot containing distinct images. For improving the realistic accuracy of images, this manuscript introduces an Itinerant Pixel-Matching-based Stitching Process (IPMSP). proposed relies on cross-sectional pixels identified...

In digital image processing, binarization (two-level thresholding) is a commonly used technique for image segmentation. It is the process of converting a gray scale image to a binary image. Furthermore, binarization methods are divided into two groups as global binarization and locally adaptive binarization. A number of binarization techniques have been proposed over the years. Bernsen’s method...
