This chapter introduces the reader to the area of parametric image registration, from a beginner’s point of view. Given a model, an input image and a reference image, the parametric registration task is to find a set of parameters (of the model) that transform the input image into the reference image. This chapter reviews models of the general projective, affine, similarity and Euclidean transf...

Hydroxyethyl starches (HES) are commonly used synthetic colloidal solution in veterinary medicine. Despite of possible adverse effect to kidney injury in human, there is no report about nephrotoxic effects of HES in dogs. HES was administered to a Golden retriever (4-year-old, intact male) with ascites in order to increase plasma osmolality. Initially, the dog was mild azotemic, however, kidney...

The computation of optical ow from image derivatives is biased in regions of non uniform gradient distributions. A least-squares or total least squares approach to computing optic ow from image derivatives even in regions of consistent ow can lead to a systematic bias dependent upon the direction of the optic ow, the distribution of the gradient directions, and the distribution of the image noi...

tyrosinase is a multifunctional copper-containing enzyme. it can catalyze two distinct reactions of melanin synthesis and benzaldehyde derivatives, which are potential tyrosinase inhibitors.  to find the relationships between charge distributions of benzaldehyde and their pharmaceutical behavior, the present study aimed at investigating nuclear quadrupole coupling constants of quadrupolare nucl...

in the recent years, the role of lox enzymes in the cause of neoplastic diseases such as colorectal, skin, pancreatic and renal cancers has been confirmed. a new series of 1,3,4-thiadiazole derivatives bearing 2-pyridyl moiety was synthesized and their cytotoxicity was assessed using mtt protocol. enzyme inhibitory activity of prepared compounds was also tested against 15-lipoxygenase-1 as nove...

in this work, different ethyl 2,4-dioxo-4-arylbutanoate derivatives were prepared and evaluated for their src kinase inhibitory activity. for this purpose, the appropriate substituted acetophenone derivatives reacted with diethyl oxalate in the presence of sodium ethoxide in dried ethanol to give the corresponding products. all compounds showed moderate activities comparing with staurosporine a...

Quinones such as 1,4-naphthoquinones are abundant in nature and naphthoquinone based natural products are known to possess anticancer activity. This pharmacophore is known to convey anticancer activity to some drugs such as streptonigrin, mitomycin A, etc. We synthesized and characterized different classes of naphthoquinone derivatives including bis naphthoquinone, 2-arylaminonaphthoquinone, be...

The quadrants' boundary intensity discontinuity a result of of the video-camera consisting of four separate A/D banks. As a result, ow estimation at the quadrant boundaries is inaccurate. The problem could be overcome by local gain compensation. The dense ow algorithms of Black and Anandan 6] is used. The algorithm's parameters were changed to achieve best measurement results. The same eeect co...
