Comparative study of Image Fusion Methods: A Review

As the size and cost of sensors decrease, sensor networks are increasingly becoming an attractive method to collect information in a given area. However, one single sensor is not capable of providing all the required information,either because of their design or because of observational constraints. One possible solution to get all the required information about a particular scene or subject is data fusion.. A small number of metrics proposed so far provide only a rough, numerical estimate of fusion performance with limited understanding of the relative merits of different fusion schemes. This paper proposes a method for comprehensive, objective, image fusion performance characterization using a fusion evaluation framework based on gradient information representation. We give the framework of the overallnbsp system and explain its USAge method. The system has many functions: image denoising, image enhancement, image registration, image segmentation, image fusion, and fusion evaluation. This paper presents a literature review on some of the image fusion techniques for image fusion like, Laplace transform, Discrete Wavelet transform based fusion, Principal component analysis (PCA) based fusion etc. Comparison of all the techniques can be the better approach fornbsp future research

Simultaneous Spectrophotometric Esti-mation Of Camylofin Dihydrochloride And Diclofenac Potassium In Tablet Dos-age Form

The accurate, precise, sensitive and economical spectrophotometric method was developed and validated for simultaneous estimation of Camylofin Dihydrochloride and Diclofenac Potassium tablet dosage form. The method employed for UV estimation was simultaneous equation method. The method employs 248 nm as ?1 and 280 nm as ?2 for formation of equations. Camylofin Dihydrochloride and Diclofenac Potassium obeys Beer's law in the concentration range 5-80 ?g/mL (r2=0.998) and 5-80 ?g/mL (r2=0.997). The mean recovery for Camylofin Dihydrochloride and Diclofenac Potassium, were found to be 99.652 ±0.2129% and 99.80 ±0.0.00307% respectively. The developed method were validated according to ICH guidelines and values of accuracy, precision and other statistical analysis were found to be in good accordance with the prescribed values. Thus the proposed methods were successfully applied for simultaneous determination of Camylofin Dihydrochloride and Diclofenac Potassium, routine analytical work

Development and Validation of Rp Hplc Mathod for the Simultaneous Estimation of Atenolol, Losartan Potassium and Hydro-chlorothiazide in Tablet Formulation

A new simple, rapid, precise and accurate assay method was developed for simultaneous estimation of Atenolol, Losartan and Hydrochlorthiazide in pure form and tablet form. The analytes were separated by RP HPLC on a RP-Purosnosphere C18 column (5 µm, 4.6mm* 250 mm).The mobile phase was methanol:water (77:23, v/v) at 1.1 mL/min flow rate satisfactorily resolve the tertiary mixture. The UV detector was operated at 230 nm for the determination of all the drugs. Linearity, accuracy and precision were found to be acceptable over the concentration ranges of 20-120 µg/ml for Atenolol and Losartan while 5-30 µg/ml for Hydrochlorthiazide with a R2 0.9999, 0.9998 and 0.9990 values respectively. The optimized methods proved to be specific, robust and accurate for the quality control of drugs in bulk drug and pharmaceutical formulations
