3d imagination of human's organs has become feasible by digital image processing techniques and algorithms via ct or mri images in recent years. in this study, a new method for reverse engineering and biomodelling of hard tissues by catia cloud points' concept has been considered. comparing with the current softwares (e.g. biobuild or mimics) has shown the new method's easiness of implementing ...

Existing research has shown that visual input significantly contributes to learning, therefore, it is paramount to use visual tools to help demonstrate engineering concepts. One of these tools, digital image analysis, can help effectively communicate complex concepts to students in a simple and understandable format as a supplement to traditional lecturing, while simultaneously enabling student...

The use of digital photography has increased over the past few years, a trend which opens the door for new and creative ways to forge images. The manipulation of images through forgery influences the perception an observer has of the depicted scene, potentially resulting in ill consequences if created with malicious intentions. This poses a need to verify the authenticity of images originating ...

The increased availability of mapped environmental data calls for better tools to analyze the spatial characteristics and information contained in those maps. Publicly available, userfriendly and universal tools are needed to foster the interdisciplinary development and application of methodologies for the extraction of image object information properties contained in digital raster maps. That ...

Digital image processing is the process of enhancing samples of image which may or may not degraded by noise and other distortion. Image Processing takes a big role to amplify and rectify of an image, video clips, medical films, designing, animations, machineries, Computer Graphics, etc. Amplify is the process of magnification with or without noise presents applying the techniques and re-checki...

The rapid growth of digital libraries (DLs) worldwide poses many new challenges for document image analysis (DIA) research and development. DLs promise to offer more people access to larger document collections, and at far greater speed, than physical libraries can. But DLs also tend, for many reasons, to serve poorly, or even to omit entirely, many types of non-digital human–legible media, suc...

objectives : to carry out in vivo and in vitro comparative pilot study to evaluate the preciseness of a newly proposed digital dental radiography setup. this setup was based on markers placed on an external frame to eliminate the measurement errors due to incorrect geometry in relative positioning of cone, teeth and the sensor. methods : five patients with previous panoramic images were selecte...

Abstract. This paper mainly describes the rectification method of digital airborne image distortion. First, according to the digital sensor model, the mathematical model of airborne image is built up for processing the geometrical data of image, which is also the key for digital rectification. Then, the principle of digital rectification is explained through discussing the direct method and the...

Ophthalmology can profit greatly from the analysis of digital images because they can aid in establishing an early diagnosis even before the first symptoms appear. This dissertation [1] contributes to the digital analysis of such images and the problems that arise along the imaging pipeline of fundus photography, a field that is commonly referred to as retinal image analysis. We have dealt with...

We propose, in this paper, a new method for Content Based Image Retrieval (CBIR) by exploiting the digital image content. Our method is based on the representation of the digital image content by a characteristics vector of the indexed image. Indeed, we have exploited the image texture to extract its characteristics and for constructing a new descriptor vector by combining the Bidimensional Hig...
