Nasir Ahmed (engineer)

He is best known for inventing the discrete cosine transform (DCT) in the early 1970s.

The DCT, first proposed by Nasir Ahmed in 1972, is the most widely used transformation technique in signal processing and data compression.

The discrete cosine transform (DCT) is a lossy compression algorithm that was first conceived by Ahmed while working at the Kansas State University, and he proposed the technique to the National Science Foundation in 1972.

The most widely used lossy compression algorithm is the discrete cosine transform (DCT), first published by Nasir Ahmed, T. Natarajan and K. R. Rao in 1974.

The DCT is the most widely used data compression transformation, the basis for most digital media standards (image, video and audio) and commonly used in digital signal processing.

An important development in image data compression was the discrete cosine transform (DCT), a lossy compression technique first proposed by Nasir Ahmed in 1972.

The DCT is the most widely used data compression transformation, the basis for most digital media standards (image, video and audio) and commonly used in digital signal processing. A DCT variant, the modified discrete cosine transform (MDCT), is used in modern audio compression formats such as MP3, Advanced Audio Coding (AAC), and Vorbis (OGG).

It was first proposed in 1972 by Nasir Ahmed, who then developed a working algorithm with T. Natarajan and K. R. Rao in 1973, before introducing it in January 1974.

It is a core component of the 1992 JPEG image compression technology developed by the JPEG Experts Group working group and standardized jointly by the ITU, ISO and IEC.

The basis for JPEG is the discrete cosine transform (DCT), a lossy image compression technique that was first proposed by Nasir Ahmed in 1972.

The DCT is the most widely used data compression transformation, the basis for most digital media standards (image, video and audio) and commonly used in digital signal processing.

DCT coding is a lossy block compression transform coding technique that was first proposed by Nasir Ahmed, who initially intended it for image compression, while he was working at Kansas State University in 1972.

He also described the discrete sine transform (DST), which is related to the DCT.

Both the DCT and the DST were described by Nasir Ahmed T. Natarajan and K.R. Rao in 1974.

The DCT is the most widely used data compression transformation, the basis for most digital media standards (image, video and audio) and commonly used in digital signal processing.

The most important compression technique is the discrete cosine transform (DCT), a lossy compression algorithm that was first proposed as an image compression technique by Nasir Ahmed at the University of Texas in 1972.

Ahmed developed a working DCT algorithm with his PhD student T. Natarajan and friend K. R. Rao in 1973, and they presented their results in a January 1974 paper.

He is credited with the co-invention of discrete cosine transform (DCT), along with Nasir Ahmed and T. Natarajan due to their landmark publication, N. Ahmed, T. Natarajan, and K. R. Rao, "Discrete Cosine Transform", IEEE Transactions on Computers, 90–93, Jan 1974.

The discrete cosine transform (DCT), a form of lossy compression, was first proposed by Nasir Ahmed in 1972.

A tutorial discussion of how it is used to achieve digital video compression in various international standards defined by ITU and MPEG (Moving Picture Experts Group) is available in a paper by K. R. Rao and J. J. Hwang which was published in 1996, and an overview was presented in two 2006 publications by Yao Wang.
