利用小波变化对金融数据进行去噪，保留数据主要趋势，采用通用阈值去噪。-Changes in the financial data using wavelet denoising, retain data key trends, using a common thresholding.

Skew detection and correction is very important task before pre-processing of an image and it is a major problem in scanned documents, if it not detected correctly it will lead wrong result in future during image analysis. During the scanning of th
