Psychovisual Redundancy In Digital Image Processing

In digital image compression three basic data redundancies can be identified and exploited. Coding redundancy Inter-pixel redundancy. As a subcategory or field of digital signal processing digital image processing has many advantages over analogue image processing. Certain information has relatively less importance for the quality of image perception. Types of data redundancy Coding Interpixel Psychovisual Coding Redundancy How to assign codes to alphabet In digital image processing Code gray level value or color value Alphabet is used conceptually General approach Find the more frequently used alphabet Use fewer bits to represent the more frequently used alphabet and use more bits for the less frequently used alphabet Coding Redundancy 2 Focus. The first kind of redundancy is called a pixel redundancy. Coding redundancy interpixel redundancy and psychovisual redundancy.

Its elimination results a loss of quantitative information.

Redundancy In Images Coding redundancy Less bits on average to encode an individual pixel Interpixel redundancy Less bits on average to encode pixel groups Psychovisual redundancy Less bits on average to represent same visual information. 169 16 1056. Enjoy the videos and music you love upload original content and share it all with friends family and the world on YouTube. Exploiting Psychovisual Redundancy Exploit variable sensitivity of humans to colors. Image compression can be. Sample green at highest spatial frequency blue at lowest.

Psychovisual redundancy in digital image processing. Discard lower order bits 4 IGS Improved Gray Scale Quantization. Data compression is achieved when one or more of these redundancies are reduced or eliminated. Its elimination results a loss of quantitative information.

Encode logintensity instead of intensity. Coding redundancy Inter-pixel redundancy. The second kind of redundancy is called a coding redundancy.

Third kind of redundancy is called a psycho visual redundancy. Exploiting Psychovisual Redundancy Exploit variable sensitivity of humans to colors. As a subcategory or field of digital signal processing digital image processing has many advantages over analogue image processing.

The wasted space consumed by storage media to Store image information in a digital image. It can be eliminated without significantly impairing the quality of image. Sample green at highest spatial frequency blue at lowest.

Psychovisual redundancyPsychovisual redundancy is associated with real or quantifiablePsychovisual redundancy is associated with real or quantifiable visual. Image compression can be. Use of less no.

N1 data. Redundancy of 09 implies that 90 of the data in the first data set is redundant. CR Coding RedundancyIR Interpixel RedundancyPVR Psycho-Visual Redundancy 5.

The Psychovisual redundancies exist because human perception does not involve quantitative analysis of every pixel or luminance value in the image. Exploiting coding redundancy interpixel redundancy and psychovisual redundancy.

Digital Image Processing Image Compression 10 Image Compression using Psychovisual Redundancy. Discard lower order bits 4 IGS Improved Gray Scale Quantization. Exploiting Psychovisual Redundancy Exploit variable sensitivity of humans to colors. Exploiting coding redundancy interpixel redundancy and psychovisual redundancy. Elimination of psychovisually redundant data from an image results in a loss of quantitative information. Third kind of redundancy is called a psycho visual redundancy. Were more sensitive to differences between dark intensities than bright ones. In digital image compression three basic data redundancies can be identified and exploited. Data compression is achieved when one or more of these redundancies are reduced or eliminated.

It can be eliminated without significantly impairing the quality of image. Data compression is achieved when one or more of these redundancies are reduced or eliminated. Its elimination is real visual information is possible only because the information itself is not essential for normal visual processing. Sample green at highest spatial frequency blue at lowest. Exploiting coding redundancy interpixel redundancy and psychovisual redundancy. Compression ratio CR n1n2Relative redundancy RD 1 1CR 4. 169 16 1056.
