hard modelling analysis of image based kinetic data

Abstract: image analysis involves image processing for extracting meaningful information, which can include noise cancellation, improved image quality and statistical calculation, and can be done both automatically and semi-automatically computer image analysis is when a computer or electrical device automatically reads an image to obtain useful information. it is usually a computer, but it may be an electrical circuit or a digital camera or even a cell phone. applications of image analysis include identification of new plant and animal species, astronomy, metallurgy, cancer diagnosis, forensics and error level analysis, and noise cancellation. . image analysis allows quantitative image evaluation .various techniques are used for automatic image analysis. each technique is possible. it is useful for a small range of tasks. therefore, various software in the field of photo analysis has been designed. [1-2]in this study two colorless reactants (n- naghtyl amine ans sulfanilic acid) were reacted to form a red diazoniuom product. the reaction was recorded for 10 mines under visible light and its move was recorded with smartphone. in the next step the movie was converted to frames in matlab and was fitted to first order kinetic model. the reaction was monitored in different initial concentrations of reactants. the reaction rate constant was also obtained as 3.599×10-5. the error of estimated parameter was estimated 1.0513×10-7. the applied method is very simple, and can be used in analysis of reactions involving a change in color without need to spectrophotometer. the reaction process is very simple and easy to do.
