Polar Fusion Technique Analysis for Evaluating the Performances of Image Fusion of Thermal and Visual Images for Human Face Recognition

This paper presents a comparative study of two different methods, which are based on fusion and polar transformation of visual and thermal images. Here, investigation is done to handle the challenges of face recognition, which include pose variations, changes in facial expression, partial occlusions, variations in illumination, rotation through different angles, change in scale etc. To overcome these obstacles we have implemented and thoroughly examined two different fusion techniques through rigorous experimentation. In the first method log-polar transformation is applied to the fused images obtained after fusion of visual and thermal images whereas in second method fusion is applied on log-polar transformed individual visual and thermal images. After this step, which is thus obtained in one form or another, Principal Component Analysis (PCA) is applied to reduce dimension of the fused images. Log-polar transformed images are capable of handling complicacies introduced by scaling and rotation. The main objective of employing fusion is to produce a fused image that provides more detailed and reliable information, which is capable to overcome the drawbacks present in the individual visual and thermal face images. Finally, those reduced fused images are classified using a multilayer perceptron neural network. The database used for the experiments conducted here is Object Tracking and Classification Beyond Visible Spectrum (OTCBVS) database benchmark thermal and visual face images. The second method has shown better performance, which is 95.71% (maximum) and on an average 93.81% as correct recognition rate.Comment: Proceedings of IEEE Workshop on Computational Intelligence in Biometrics and Identity Management (IEEE CIBIM 2011), Paris, France, April 11 - 15, 201

Mikoplazmalna pneumonija u Garole ovaca.

The prevalence of spontaneous pneumonia in Garole sheep was reported based on isolation of Mycoplasma and pathological changes. Mycoplasmal isolate was provisionally identified as Mycoplasma ovipneumoniae by cultural characters and biochemical changes. Pathological changes featured interstitial pneumonia with peribronchial and perivascular lymphoid cell hyperplasia and thickening of interlobular septa.Pri pojavi pneumonije u Garole ovaca izdvojene su mikoplazme te prikazane patološke promjene. Izdvojeni izolat je na osnovi kulturelnih i biokemijskih značajki identificiran kao Mycoplasma ovipneumoniae. Patološke promjene očitovale su se intersticijskom pneumonijom s peribronhalnom i perivaskularnom hiperplazijom limfoidnih stanica te zadebljanjem interlobularnih septi

Blood Brain Barrier: A Challenge for Effectual Therapy of Brain Tumors

Brain tumors are one of the most formidable diseases of mankind. They have only a fair to poor prognosis and high relapse rate. One of the major causes of extreme difficulty in brain tumor treatment is the presence of blood brain barrier (BBB). BBB comprises different molecular components and transport systems, which in turn create efflux machinery or hindrance for the entry of several drugs in brain.Thus, along with the conventional techniques, successful modification of drug delivery and novel therapeutic strategies are needed to overcome this obstacle for treatment of brain tumors. In this review, we have elucidated some critical insights into the composition and function of BBB and along with it we have discussed the effective methods for delivery of drugs to the brain and therapeutic strategies overcoming the barrier
