MOTIVATION The major signal in coding regions of genomic sequences is a three-base periodicity. Our aim is to use Fourier techniques to analyse this periodicity, and thereby to develop a tool to recognize coding regions in genomic DNA. RESULT The three-base periodicity in the nucleotide arrangement is evidenced as a sharp peak at frequency f = 1/3 in the(More)
In this paper, an adaptive color image enhancement based on geometric mean filter is proposed. The contrast of the color image is enhanced by using saturation feedback from saturation components and incorporating spatial information into luminance components. Hue is preserved in order to avoid color distortion. The adaptive luminance enhancement is achieved(More)
A novel block matching algorithm for motion estimation in a video frame sequence, well suited for a high performance FPGA implementation is presented in this paper. The algorithm is up to 40% faster when compared to one of the fastest existing algorithms, viz., one-at-a-time step search algorithm without compromising either in the image quality or in the(More)
OBJECTIVES The present investigation was aimed to study the antidiabetic and antihyperlipidemic potential of Abelmoschus esculentus peel and seed powder (AEPP and AESP) in streptozotocin (STZ)-induced diabetic rats. MATERIALS AND METHODS Acute toxicity of AEPP and AESP was studied in rats at 2000 mg/kg dose and diabetes was induced in rats by(More)
