The perceptual based techniques help in reducing the noise by taking advantage of the masking properties of the auditory system.
In this work we propose an optimization of the E_LTW encoder with the aim to increase its R/D performance through perceptual encoding techniques and reduce the encoding time by means of a graphics processing unit-optimized version of the two-dimensional discrete wavelet transform.
The concept of this perceptual grouping technique is briefly described as follows.
This paper presents a new method for edge-preserving color image denoising based on the tensor voting framework, a robust perceptual grouping technique used to extract salient information from noisy data.
The improvement in LG's right eye was higher (109%) than the average reported improvement (about 80%) that follows a similar perceptual learning technique for amblyopia and presbyopia (Polat, 2008, 2009a; Polat et al., 2004; Polat et al., 2012).
It is possible that perceptual training using techniques other than the UFOV could also be efficacious for enhancing driving ability among populations of older adults with different functional limitations.
Initially, we also tried to increase the diversity of the key by using technique relying on perceptual hashing, but this technique was not mature enough to be implemented in the last final version of the algorithm.
Therefore, we decided to use objective quality assessment metrics whose design is inspired by the HVS, since our proposal includes perceptual-based encoding techniques that may not be properly evaluated by the PSNR metric.
These include the genetic bases of cognitive and perceptual hardware, concepts, languages, techniques, beliefs, preferences, and so forth.
Section 4 introduces the data hiding framework for managing privacy information and various embedding techniques and perceptual distortion and rate models.
