A new image quality metric based on human visual system
2012 Edition, July 1, 2012 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper we propose a new image quality metric based on human visual system (HVS) called PSNR-JND. This metric is based on the values of DCT coefficients of 8×8 pixel block of an image. In particular, it assumes the same formula as...

Enhancement and evaluation of the geophysical inversion model based on the human visual system
2013 Edition, January 1, 2013 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Geophysical inversion algorithms often introduce artifacts near sharp intensity transitions and image boundary. We presented a iterative restoration algorithms to restore the true inversion image and remove the artifacts. We also presented a ringing metric to evaluate the...

Multiple Description Video Coding Based on Human Visual System Characteristics
2014 Edition, Volume 24, August 1, 2014 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper, a novel multiple description video coding scheme is proposed based on the characteristics of the human visual system (HVS). Due to the underlying spatial-temporal masking properties, human eyes cannot sense any changes...

Fuzzy Blocking Artifacts Reduction Algorithm Based on Human Visual System
2007 Edition, Volume 3, August 1, 2007 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Traditional blocking artifacts reduction algorithm often causes image edges losing. To address this problem, a fuzzy edge-sensitivity blocking artifacts reduction algorithm is proposed. Based on some characteristics of human visual system, this algorithm applies...

High quality Motion JPEG2000 coding scheme based on the human visual system
2005 Edition, January 1, 2005 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A novel high quality Motion JPEG2000 coding scheme is proposed, which is based on the human visual system being insensitive to the high frequency components of an image. This method enhances subjective video quality by controlling the amount...

Video quality enhancement for Motion JPEG2000 encoding based on the human visual system
2004 Edition, Volume 2, January 1, 2004 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A novel Motion JPEG2000 encoding method is proposed, which is based on the human visual system being insensitive to high frequency component of image. This method enhances subjective video quality by controlling bitrate of each region, such as a tile or a...

Subpixel rendering for the pentile display based on the human visual system
2017 Edition, Volume 63, November 1, 2017 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Recently, with the increased demand for low-power displays regarding portable devices, the RGBG PenTile display is popularly utilized. However, unlike the traditional RGB-stripe display with its three color channels, each pixel of the RGBG PenTile display comprises only...

Multiresolution images based on human visual system characteristic
2001 Edition, Volume 2, January 1, 2001 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In digitizing, an image is usually sampled with an invariable frequency. For the high frequency part of the image, which plays an important role in the visual effect, the sampling is illogical. To overcome the limitation, the wavelet transform...

Variable Frame Rates Control Strategy Based on Human Visual System
2005 Edition, Volume 1, January 1, 2005 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

One rate control algorithm using human visual system (HVS) for block-based video coding is presented. Rate control algorithms may not achieve a good balance between spatial and temporal quality automatically and are not suitable for bandwidth fluctuation situation. To...

A Hybrid Image Compression Algorithm based on Human visual system
2010 Edition, Volume 9, October 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper, we present an efficient hybrid image compression method. According to Human eye sensitivity, It is not sensitive to gray-scale error, but the human eye is particularly sensitive to the image edge features, through we research strengths and weaknesses of...
