We present a new technique for content based image retrieval using motif cooccurrence matrix (MCM). The MCM is derived from the motif transformed image. The whole image is divided into 2 £ 2 pixel grids. Each grid is replaced by a scan motif that minimizes the local gradient while traversing the 2 £ 2 grid forming a motif transformed image. The MCM is then defined as a 3D matrix whose ði; j; kÞ...

Variational models with 1-norm based regularization, in particular total variation (TV) and its variants, have long been known to offer superior image restoration quality, but processing speed remained a bottleneck, preventing their widespread use in the practice of color image processing. In this paper, by extending the grayscale image deblurring algorithm proposed in [Y. Wang, J. Yang, W. Yin...
We propose a new multiscale image decomposition which offers a hierarchical, adaptive representation for the different features in general images. The starting point is a variational decomposition of an image, f = u0 + v0, where [u0, v0] is the minimizer of a J-functional, J(f, λ0;X,Y ) = infu+v=f { ‖u‖X + λ0‖v‖pY } . Such minimizers are standard tools for image manipulations (e.g., denoising, ...
Endoscopic image enhancement has become a very popular research field due to the success of minimally invasive interventions and the innovation of new technological treatment and diagnosis tools such as stereoscopic laparoscopes and the wireless capsule endoscopy. In spite of the important advances achieved in terms of image processing and enhancement, only a few techniques can be adapted to st...
در این پایان نامه تعریفی جدید از قاب ها برای فضاهای کرین ارائه شده است که توسیع مفهوم پایه های متعامد در فضای کرین است. ??j است؛ این قاب با h یک قاب خاص در فضای هیلبرت (h; [; ]) قاب برای فضای کرین ??j یک معین اکیداً ??j سازگارست؛ به این معناست که با یک زوج از زیرفضاهای [; ] ضرب داخلی نامعین ماکزیمال با زیرفضاهای مثبت متفاوت معین می شود. قاب ??j متعامد سازگار است؛ همچنین هر ??j این قاب ها با...
فرض کنید r حلقه جابجایی و نوتری وi وj ایده آل هایی از r باشند. اگر r حلقه ی موضعی با ایده آل ماکزیمال m باشد، ثابت می کنیم: تساوی inf{ i |?? h?_(i,j)?^i(m) آرتینی نیست }= inf { depthm_p ? p? w(i,j){m}} برقرار است که در آن m یک r – مدول متناهی مولد است و w(i,j)={ p? spec(r): i^(n )?p+j ,? n?1}. 2.برای هر r- مدول متناهی مولد m با بعد d، ?? h?_(i,j)?^d(m) آرتینی است. در وقع سوپریمم اعداد ...
The novel ENEA-INMRI Image Analyzer system has been tested in semi-automated mode for a computer-assisted alpha track counting of electro-chemically etched (ECE) and chemically etched CR-39 Solid State Nuclear Track Detector (SSNTD) chips. A track recognition program based on the Java-Image J processing software was developed. Experimental tests have been carried out to maximize the Field of Vi...
