    Image enhancement is the process of modification of digital images in order to make quality resultant images such that those can be subjected to further manipulation (like further image analysis). There are several ways to implement image enhancement techniques. In this paper, we have studied a number of image enhancement methods consisting of binarization techniques and hybridization of such techniques. After applying those methods on scanned Bangla document images, we have analyzed the reconstructed images. Then, we have gone for the quantitative analysis portion. To accomplish that, we have measured the recognition rate and then examined the improvement ratio of the unprocessed samples versus reconstructed images in terms of recognition rate. Our analysis critically emphasizes the requirement to apply image enhancement methods. This study will certainly help the researchers to select appropriate image enhancement method(s) for processing low quality Bangla printed document images.

    An improved chromosome sorting algorithm by permutation group-based inverted block-interchanges

    In comparative genomics, a common issue is to find the shortest course of operations for the transformation of one genome into another. During rejoining the blocks, inverted block interchange, a more distinct form of block interchange, gives the option to the blocks to reverse their orientation. In this particular paper, we have presented an improved algorithm to sort circular chromosomes by inverted block interchanges and also compared the performances with a previous algorithm. Our experimental findings justify the fact that accommodation of inverted block interchange ensures results with equal or less number of series of operations in terms of block interchanges.
