An artificial intelligence algorithm for a computer game competition organised by Google and University ofWaterloo is presented. It competes with others by reasoning, evaluating of a situation and taking decisions in a war simulation.
The paper presents an evaluation of Polish phone segmentation for different types of phones. The categorisation was done based on acoustic properties. The segmentation method is based on discrete wavelet transform and was already published. The results show that several types of transitions, especially from and to vowels cause more errors than others.
A transmultiplexer assigned to combine images into one image to be sent through a single communication channel is presented. The considered system can be equipped with integer-to-integer filters to enable the lossless compression. The efficiency of lossless JPEG compression applied to transmultiplexed signals has been verified
The application of image compression methods in transmultiplexer systems is presented. The specific energy distribution in the combined image spectrum makes the standard compression methods, especially these that base on frequency decomposition not efficient. Two cases are described and compared: the compression of combined image and the preliminary compression of input images before transmultiplexing...
In this paper a new method of speech segmentation is suggested. It is based on power fluctuations of the wavelet spectrum for a speech signal. In most approaches to speech recognition, the speech signals are segmented using constant-time segmentation. Constant segmentation needs to use windows to decrease the boundary distortions. A more natural approach is to segment the speech signals on the basis...
