Keystroke dynamic is one of the behavioral biometric identification techniques which distinguish users through their unique typing style. This paper presents two techniques to measure the distance metric between two samples of the same user. Two methods are used to implement the normalized distance between two samples of the same user; first method uses JavaScript for measuring the feature extraction...
Gaussian smoothing filters are commonly used in various image processing applications to reduce the noise level in an image. The filters are particularly popular in edge detection algorithms because of their ability to smooth false edges and improve the edge detection performance. When implemented on a fixed-point computational platform, the filter coefficients are rounded and the implemented filter...
This paper describes a high throughput encoder for high dynamic range (HDR) images that is compatible with the JPEG2000 engine. A nine-level Reinhard-like tone mapping operator is used to calculate a local illumination estimate around each pixel in the image. Both, the local illumination estimate and the tone mapped pixel streams are sent to the JPEG2000 engine for compression. When tested with HDR...
