Abstract

Technically, there are many ways to store, transmit, receive and display images. One of these methods is the JPEG format, which is a lossy image compression format. This format relies on removing high frequencies (details) from the image that cannot be detected by the human eye before storing the image.

The aim of the research is to focus on applying two trigonometric functions (sin, cos) to the image before performing the JPEG compression process and then measuring the amount of compression and file size before and after applying the trigonometric functions.

The research hypotheses discuss that the amount of data loss in the image after applying the trigonometric functions affects the information in the image and the size of the image on the storage media is less.

Research problem: Questions have been raised about the necessity of increasing the image compression rate with minimal loss of information and image quality when used in media production.

The research concluded that by applying one of these trigonometric functions, compression is relatively better and data loss is the same or less than information loss.
