Meaning: n. (psychophysics) the difference between two stimuli that (under properly controlled experimental conditions) is detected as often as it is undetected.
Random good picture Not show
1. The JND model is one of classic metrics in objective perceptual video quality research.
2. Furthermore, for human visual perception, the scaling JND model is developed to optimize the reconstructed image quality.
3. Photo Scavenger Hunt IdeasIt gets people working jnd laughing together, requires little equipment and has lots of room for creativity.
4. The robustness of JND plays a key role in blind watermark detection.
4. Sentencedict.com try its best to collect and make good sentences.
5. It is based on JND model which provides the maximum amount of watermark signal that can be tolerated at every image location without affecting the visual quality of the image.
6. We have twenty branches abroad, jnd we've recently opened a new one in Bangkok.
7. He lives at jnd.org.
8. Introduces the concepts of watermarking channel, discusses the problem of the watermarking capacities in the still image by using the information theoretics on the base of JND model.
9. Then, two extreme regions, i. e. , the luminance adaptation extreme regions for smooth blocks and contrast masking extreme regions for detailed blocks, were determined by the JND profile.
10. This work was undertaken by using the flicker method and JND Technique.
11. Through the study of whole watermarking system, a novel JND computation method is proposed, which enhances the robustness of JND threshold.
12. In image watermarking system, a satisfying result can be obtained where JND threshold is used to control the embedding location and intensity and determine the extraction location in blind algorithm.
13. Against the bit error when the picture is compressed, with JND model in order to keep invisible, a new bit error correction method is proposed based on extraction-comparison.
