Sentence examples for human visual distortion from inspiring English sources

If the gray level difference between the background and the object is smaller than that of the human visual distortion denoted as the JND value, the object could not be detected visually.

Therefore, the human visual distortion criterion of an MB is determined by this characteristic.

This concept of the human visual distortion of the gray level difference can be extended to the temporal domain.

Knowledge about human visual luminance distortion was provided by this model.

This would let him produce low frequency sounds (under 20Hz) at a painful 145dB, causing some pretty weird and debilitating effects in humans, including visual distortion, nausea, and even (at high volume) rupturing eardrums and internal organs.

Third, JND model, which refers to the maximum distortion that human visual system cannot perceive, is extended from spatial domain to temporal domain so as to determine perceptual cue in unit of MB.

In a previous work [13], both subjective and objective tests were performed to establish the sensitivity of the human visual system to the geometric distortions introduced by the LPCD model as a function of the control parameters and.

Instead, we adopt the DCT perceptual model proposed by Watson [33], which has been shown to better correlate with the human visual system than standard mean square distortion.

That is, the amount of filtering is adjusted to the perceptual distortion by integrating a human visual system model into filtering based on luminance, activity and temporal masking.

Specifically, the non-linear prediction adopted by JPEG-LS is further exploited to indicate: (i) the compressibility of each local region inside the input image; (ii) the distortion tolerance according to human visual perception.

The distortion is based on human visual system and a perceptual mask in DCT domain is used to facilitate the calculation.
