Correlation between objective and subjective methods used for video quality evaluation

The article deals with the correlation between the objective and the subjective methods. In the first part the short characteristic of the MPEG compression standards is written. The second part focuses on the objective metrics and the third part on the subjective methods, which were used for testing. In the fourth part regression and correlation analysis are written. In the fifth part the measurements and the experimental results using the objective metrics and in the fifth part the measurements and the experimental results using the subjective methods are described. The last part deals with the correlation between the objective and the subjective methods, mapping and approximation

CATV network evolution

Cable television (CATV) distributions are transmissions systems assigned for received and distribution televisions (TV) and radios (R) signals. This paragraph is about individual stages of evolution of this distribution. It begins by classic CATV network by using coaxial cable then it continues by modernization of optical fibre. It describes structure and two-way communication of interactive TV cable distribution frame and it describes intelligence of this network. By implementation interactivity we can not understand it as the CATV network as only distributions system which transfers only TV and R signals but like multifunctional system which can transfer information by both directions

Impact of compression on the video quality

This article deals with the impact of compression on the video quality. In the first part, a short characteristic of the most used MPEG compression standards is written. In the second part, the parameter Group of Picture (GOP) with particular I, P, B frames is explained. The third part focuses on the objective metrics which were used for evaluating the video quality. In the fourth part, the measurements and the experimental results are described

3D Modelling, Animation and Simulation of Mammal’s Migration Across Roads

The presented article is dealing with the new methods which are designated for data collection of mammals migrating across traffic networks. Nowadays, road construction and securing of older roads is usually accompanied by finding new solutions. Because of lack of collected data we have new opportunities how we can collect this input. The article below describes the most efficient method which is suitable for the model creation, process of creation and issues which are connected with the creation of simulations
