In this paper the latest researches on YCrCb color optimization, TV images compression basing on the dynamic objects selection, algorithms of signals sources isolation and examination of mechanical influence on an optical fiber by digital holographic interferometry methods are discussed. In the new color space based on YCrCb every color has its own luminance value and there are no essential color tone changes and color distortion after the brightness editing.
In the article the scientific researches of the newest effective compression method for the
video information are considered. Basic advantage of this method was displayed and testing
comparison of the results was showed. Method of the interframe difference could be used for
the video compression within single video-scene where the video camera movements almost
immobile. Also, this method could be used in addition with other methods like parameter
models. The main schemas algorithms were illustrated in detail. Also the basic requirement
for this method implementation and its main defect were shown up and explored with possible
solving for these problems. The main data from illustrated table shows that this method has an
advantage in comparison with others only when the commutated video frames has static background. That makes this method useful only in specific video-scenes. The represented
method was developed as an addition to the others methods that could be used in videocodec.
Also algorithms of separation of the source signals and showed the results of mathematical
modeling of these algorithms are described. The prospects for utilization of modern information technology achievements in the field of digital image processing for precision measurements of phase distortions arising in communication optical fiber under external mechanical influence are discussed. The measurement method based on two exposition digital holographic interferometer is proposed. The circuit of measurements and the programming algorithm of digital image processing are described. The measurement procedure and experimental results are presented. The opportunities of measurement method for monitoring of the telecommunication equipment are
discussed.
