Adaptive median filtering method was mainly used for filtering Salt&Pepper (impulse) noise, while the method based on Curvelet transform was mainly used for filtering Gaussian noise. In the actual processing for sealed rubber ring image, which usually contains the mixture of Salt&Pepper noise and Gaussian noise. In order to filter out the mixed noisy image preferably, a new mixed filtering...
When, constructing the scale space of fast Hessian detector in SURF, using integral image and box filters to approximate the Gaussian second order derivative filters is the most pivotal step. The common algorithm for this is firstly calculating the pixels' sums in each sub-rectangle region of a mask, then multiplying the coefficients and adding them together. This way may cause some repeatable calculations,...
In this paper, through the study of the existing collaborative filtering technologies and the e-commerce recommendation system concepts, architecture and the main recommendation technology and development, an improved collaborative filtering algorithm is designed and implemented. This algorithm can solve the scalability problem general collaborative filtering algorithms can not solve to some extent,...
