This paper proposes a new design of gesture controlled MP3 player method based on triaxial accelerometer MMA7260, and in program applying the matching algorithm —using shaking times to match the operation instructions. The experimental results shows that the design can make MP3 player play, stop, play back, play forward and so on.
Traditional bilinear scaling method requires pre-zoom operation while zooming-out an image. In that way, the image resizing system will demand two different scaling sets, one for zooming-out and another for zooming-in, and hence leads to higher cost of hardware implementation and system complication. This paper presents an improved scaling method called window-scaling algorithm. It is relatively low...
Bi-cubic interpolation algorithm is commonly used in image scaling, but traditional cubic interpolation has its own shortcomings such as complicated computation, long computational time and so on. For these problems, the paper studies traditional cubic kernel function and proposes an optimized algorithm with adjustable coefficients. This algorithm utilizes an modifying coefficient lambda to amend...
