- More Than Just the Kappa Coefficient: A Program to Fully Characterize Inter-Rater Reliability Between Two Raters
- The kappa coefficient is a widely used statistic for measuring the degree of reliability between raters. SAS procedures and macros exist for calculating kappa with two or more raters, but none address situations when the kappa coefficient alone does not sufficiently describe the level of reliability. When the prevalence of...

- Iris Identification Using 2D Wavelet 1.0 (Windows)
- Iris structure has complex and plentiful textures which can be extracted as features for iris coding. We present a new representation of iris coding by using 2D wavelet. The proposed scheme of feature extraction is to use the multi-level coefficients of decomposition parts of image via wavelet. A feature vector...

- GA-Based Optimization of Sigma-Delta Modulators for Wireless Transceivers
- Over-sampling sigma-delta Analog-to-Digital Converters ADCs are one of the key building blocks of state of the art wireless transceivers. In sigma-delta modulator design, the scaling coefficients determine the peak signal-to-noise ratio. Therefore, selecting the optimum value of the coefficient is very important. To this end, this paper addresses the design...

- Face Recognition Based On Overlapping DCT 1 (Windows)
- Face Recognition Based On Overlapping DCT - Matlab source code. In the JPEG image compression algorithm, the input image is divided into 8-by-8 or 16-by-16 blocks, and the two-dimensional DCT is computed for each block. The DCT coefficients are then quantized, coded, and transmitted. The JPEG receiver (or JPEG file...

- CoolLotto 1.1 (Windows)
- CoolLotto is a simple but effective gaming tool. It allows to analyze intended lotto numbers, and see how likely they are to be drawn. The program uses two statistical coefficients developed for this purpose (called: the Punch and the Spread). The coefficients inform the player about the hidden regularities within...

- Wavelet-Neural Networks Based Face Recognition 1 (Windows)
- Wavelet-Neural Networks Based Face Recognition System - Matlab source code. Wavelet transforms are used to reduce image information redundancy because only a subset of the transform coefficients are necessary to preserve the most important facial features such as hair outline, eyes and mouth. We demonstrate experimentally that when Wavelet coefficients...

- Neural Networks - DCT for Face Identification 1 (Windows)
- Neural Networks - DCT for Face Identification. Matlab source code. High information redundancy and correlation in face images result in inefficiencies when such images are used directly for recognition. Discrete cosine transforms are used to reduce image information redundancy because only a subset of the transform coefficients are necessary to...
