Using VC++6.0 or Matlab language realize 2-D wavelet image transform and untransformed, Huffman encoding and decoding ,N order context adaptive arithmetic encoding and decoding, run length encoding and decoding, DPCM encoding and decoding, and wavelet transform, EZW encoding, Huffman encoding, N order context adaptive arithmetic encoding to compress a static image, directly get actual compressive /reconstructiveimage, the compression ratio and psnr objective appraise index.
Objective To investigate the shortest exposure time resulted in temporary threshold shift and a sensitive objective evaluated method in long-term noise exposures, through exploring the effect of various durations of noise exposure on auditoiy brainstem response (ABR) and distortion product otoacoustic emissions (DPOAE) in Rats.
We conclude that CRA enforcement during this period reflected, at least in part, objective evaluation criteria.
It is important then that there be comprehensive and objective evaluation criteria for all these measurable aspects of distance education.
Objective evaluation criteria for 2d-shape estimation results of moving objects.
That is, the subjectivity of image perception prevents us from defining objective evaluation criteria.
The concept selection decisions were illstructured due to a lack of objective evaluation criteria for the decision makers.
In this paper, the author deals with the relation between cross cor-relation coefficient and sound-articulation in halls, and also points out that it is possible to use the coefficient mentioned above as the objective criterion for evaluating the sound-articulation in halls.
This paper defines two specifications and derives several equations for evaluation of the performance of the two error control methods used in CCITT No.7 signaling system. The situations which are suitable for these two methods have been discussed also.
In the paper, objective evaluation indices of gear shifting smoothness in power-shift transmission in wheel type construction machines are presented, together with a mechanical and mathematical model and measures to improve the gear shifting smoothness.
