the Statistical estimation of result of programm modelling of algorithms of compression and restoration of images

Characteristic line for the statistical analysis is that they will convert assemblage of value judgment in objective, by obediyonenija assemblage of difficult individual researches in the unique estimation concretised by certain criteria.

At conducting of statistical research there is a set osyonovnyh techniques which includes:

— Statistical observation;

— A report and a group of results of statistical observation;

— Absolute and relative statistical magnitudes;

— Variation rows;

— Sample;

— Correlation and regressionnyj the analysis;

— Dynamics rows.

Because dissertational work is connected with machining izobrayozheny, and perception of such criterion as quality rebuilt izobrayozhenija, is subjective, in the capacity of an estimation method the method of statistical observation was applied.

Such method of research is under control, in advance organiyozovannym and, as a rule, statistical property data acquisition. Application of the given method is caused by registration of in advance certain key criteria, reception concrete uzyokospetsialnyh characteristics of studied installation costs a problem of such method.

At performance of statistical observation there is a number osnovyonyh demands:

1) Observation should cover completely studying area predyometa;

2) Results of research should be objective and exact;

3) the Output information should be systematised and have the general criteria of an estimation.

There are two basic forms of statistical observation:

1) Specially organised observation - observation, organizoyovannoe with specific target statement, for data acquisition which have not been presented earlier or for check of results previous issleyodovany. For example, variety of such form statistical nabljudeyonija are sociological interrogations, the account and registration of migrants, etc.

2) the Papework is an aspect of statistical observation the information is store uped directly in the profile organisations or establishments. At such aspect of research all results are brought in in advance prepared form of the papework.

One more aspect of classification of statistical researches is based on two key signs:

1) On character of the account and registration of results;

2) On a quantity indicator of the spent researches.

To the first type it is possible to refer to such procedures, as: interrogation, protokoyolirovanie etc., and to the second type - selective or continuous observation.

For reception of statistical data in the dissertation statistical observation (questioning and correspondent dejatelyonost) was used.

For reception of the statistical estimation, the results of restoration of the image gained at modelling sociological interrogation is spent.

Highly skilled specialists participated in interrogation proyomyshlennoj branches in number of thirty persons, different age, dolzhyonostej and an operational experience.

Interrogation was spent in the form of the test. Results of interrogation are inferred visually on the diagrammes presented in drawings 3.9 and 3.10.

By results of interrogation obvious regularity is observed: vospriyojatie images does not depend on age interrogated and their qualifications.

According to interrogation of 95 % interviewed consider, that:

— The distortions which have originated during restoration of the image, not vliyojajut on perception;

— Rebuilt, also are identical.

Conformity to the standard

sootvetstvuet "There are deviations

Drawing 3.9 - Distribution of results of interrogation to conformity

The rebuilt image to the reference

Only 5 % of the interrogated have considered, that there are insignificant deviations

In the capacity of rebuilt image from the standard. However have confirmed,


That at such deficiencies integrity of perception is not broken.

Drawing 3.10 - Distribution of results of interrogation to conformity vosprijayotija the rebuilt image reference

By results of the spent interrogation it is possible to draw a leading-out, that predyostavlennye in-process algorithms of compression and restoration of images at the remote control of critical computer systems work koryorektno and they can be referred to to algorithms of compression without quality loss vospriyojatija.
