TL;DR: In this paper, the authors examined and evaluated the use of wavelet packet transforms for urban texture analysis and image classification in high spatial resolution LISS IV imagery, which provided more details of the urban areas.
Abstract: Texture in high resolution satellite images requires substantial amendment in the conventional segmentation algorithms. This study examined and evaluated the use of wavelet packet transforms for urban texture analysis and image classification in high spatial resolution LISS IV imagery, which provide more details of the urban areas. This paper analyzes the performance of the combination of Wavelet Statistical Features (WSFs) and Wavelet Co-occurrence Features for the classification of LISS IV images. Per pixel classification accuracy is improved in this work by varying the window size. Four indices (user's accuracy, producer's accuracy, overall accuracy and kappa coefficient) are used to assess the accuracy of the classified data. Experimental results show that a multi-band and multi-level wavelet packet approach can be used to drastically increase the classification accuracy.

TL;DR: It was found that at concentration above 0.1 % (w/v) PAA, the PGA production decreased, and this selective condition paves the way for less costly bioprocess for the production of PGA.
Abstract: Bacillus badius isolated from soil has been identified as potential producer of penicillin G acylase (PGA). In the present study, batch experiments performed at optimized inoculum size, temperature, pH, and agitation yielded a maximum PGA of 9.5 U/ml in shake flask. The experiments conducted in bioreactor with different oxygen flow rates revealed that 0.66 vvm oxygen flow rate could be sufficient for the maximum PGA activity of 12.7 U/ml. From a detailed investigation on the strategies of the addition of phenyl acetic acid (PAA) for increasing the production of PGA, it was found that the controlled addition of 10 ml of 0.1 % (w/v) PAA once in every 2 h from 6th hour of growth showed the maximum PGA activity of 32 U/ml. Thus, our studies for the first time showed that at concentration above 0.1 % (w/v) PAA, the PGA production decreased. This selective condition paves the way for less costly bioprocess for the production of PGA.
