Gene Prediction Based on One-Dimensional Image Segmentation

摘要：

　　In the current study,using methods of signal processing to rouge gene prediction has attracted great attention.At first,the voss mapping which can map the DNA alphabetic sequence into the numerical sequence and the 3-base periodicity of exon are introduced.Then a fixed-length sliding window approach and its feasibility are analyzed.It can be proved that when two exons are very close,gene prediction by only setting a threshold to the spectrum could not have good effect.To overcome this shortcoming,a new method based on one-dimensional image segmentation is proposed.Finally,simulation shows the short introns are culled commendably.Two evaluation indices arc also introduced to demonstrate the effectiveness of this method.
