We propose a signal processing approach for detecting enrichment regions from ChIP-seq datasets. A wavelet transform of the ChIP-seq data offers a direct visualization for both short- and long-range patterns of the genome-wide mapping profile for protein binding site on DNA. To investigate the location of transcription factor binding site (TFBS) from ChIP-seq data, a wavelet-based peak detection algorithm...
The following topics are dealt with: signal processing and statistical approaches for functional genomics; computational biology; computational genomics and epigenomics; personal sequencing; discovery of molecular signatures and biomarkers; gene and protein sequence analysis; analysis of microarray and mass spectrometry data; denoising and compression of genomic data; regulatory network modeling,...
A filtering technique for the location of hot spots in proteins proposed recently is applied for the location of exons in DNA sequences. The technique involves conversion of a DNA character sequence into a numerical sequence using the electron-ion interaction potential values and then filtering the numerical sequence using a narrowband bandpass digital filter whose passband is centered at the period-3...
In this paper, a computer application program to process electronic microscope images of plant pollen is presented. We use contrast enhancement to separate pure object pollen from original image. Hough edge detector is used to extract complete and inside-detail-kept edges from pure object image for recognition. Pre-process such as smoothing, grayscale equipoise, etc., is performed to remove noise...
