The Story Of India-Born Nasir Ahmed Changed The World Video & Image Transfer


Nasir Ahmed: Many of the creators who created the technological underpinnings that transformed the course of humanity are often forgotten, sometimes by history and sometimes by circumstance. Nasir Ahmed, the man behind the breakthrough that allows for picture and video transmission, is one of these pioneers.

The “discrete cosine transform” developed by Nasir Ahmed is a commonly used transformation technique in signal processing and data reduction. In other words, you should thank Nasir Ahmed every time you transmit an image or a video on any social media platform or watch Netflix in high HD.

Ahmed went to the United States in 1961 to pursue a Master’s degree. He was born in Bengaluru, Karnataka. Nasir Ahmed coined the term “discrete cosine transform” while working on his PhD at the University of New Mexico.

“I had no idea that would turn into such a significant impact… Digital technology was just getting started at the time “In a video, he stated.

In an interview, Nasir Ahmed remarked, “The algorithm became the most efficient means of taking an image or a video, processing it in a way that it could be compressed and transmitted to any destination that you want.”

Almost every programme that facilitates data transmission (particularly photographs and videos), such as Zoom and Facetime, uses the technology. “It makes me really pleased,” Ahmed expressed his delight.

After his narrative was recreated and performed on the hit US show “This is Us,” Nasir Ahmed’s contribution to technology was highlighted.

DCT has a wide range of applications.

Are you curious about the applications of the discrete cosine transform (DCT)? DCT is the driving force behind all high-definition image and video delivery in the modern world, from JPEG images to MPEG-1/MPEG-2/MPEG-4 to Google’s WebP Images and WebM Video.

Could you imagine surviving the ongoing Covid-19 pandemic without technology that facilitates picture and video transmission, whether for communication or entertainment? We are unable to do so.
