This contribution evaluates the impact of chroma subsampling using two different downsampling filters using objective metric. Objective results show that distributing 4:4:4 is more efficient than its 4:2:0 counterpart for medium to high bit-rates. For low bit-rates, this increase in efficiency is reduced and in some cases even reversed.

In the article a method of compression of High Dynamic Range of Infrared images and its details enhancement was proposed. The method is based on aggregation of partial images with different ranges of pixel values generated on the basis of weighting function. Aggregation of images could be performed according to proposed scheme with use of the optimal algorithm selected by user. Preliminary resu...

nowadays, it is common to find optimal point of the dynamic problem; dynamic problems whose optimal point changes over time require algorithms which dynamically adapt the search space instability. in the most of them, the exploitation of some information from the past allows to quickly adapt after an environmental change (some optimal points change). this is the idea underlining the use of memo...

In the field of solar radio, the high performance solar radio receiver which has high sensitivity, large dynamic range is necessary to observe the radio storm fine structure. The low noise floor solar radio receiver can meet the observation request. By the theory analysis of the radio storm receiver’s noise floor and combining with the characteristic of solar radio storm, the paper submits a me...

ôbjective: this study has been conducted to investigate the efficacy of short-term dynamic psychotherapy on love trauma syndrome (lts) in female students. lts includes a constellation of intensive signs and symptoms which appear following the breakdown of a romantic relationship after a long time. ït interrupts person's function in many areas (academic, social or professional) and leads to...

Computerized dynamic assessment has been proposed as a solution to the practicality issues involved in ordinary dynamic assessment procedures. However, most of computerized dynamic assessment studies have addressed receptive skills (i.e., reading and listening). Responding to the scarcity of CDA studies of productive skills, the present study was an attempt to design and implement a computerize...

Real-time substructuring is a novel hybrid method for the dynamic testing of complex engineering structures. This technique involves creating a hybrid model of the entire structure by combining an experimental test piece with the remainder of the structure being modelled numerically. The essence of this technique is to emulate the dynamic behaviour of the complete original structure by using re...
