Traditional OTA (Online Travel Agent) is challenged by the Internet and mobile business with the evolution of information. The precise forecasting of ticket sales in OTA companies is beneficial to budget control and service quality. The paper develops an integrated forecasting model by combining the internal factors immediately influencing the ticket sales and the external factors reflecting the ticket...
This paper proposed LSB Information Hiding algorithm which can Lift wavelet transform image. Furthermore, made the objective evaluation of image quality by the peak signal to noise ratio and normalized cross correlation coefficient. Achieving the purpose of information hiding with the secret bits of information to replace the random noise, using the lowest plane embedding secret information to avoid...
A new method of fingerprint recognition was proposed. After image gathered from scanner, it was enhanced and binarized, the ridges of fingerprint image were thinned, then used freeman chain code derivation to describe the extracted fingerprint ridge, matching based on fingerprint ridge contour, and this method has the translation and rotation invariance. The algorithm was programmed with C and VC++...
