Which compression method is referred to as Intra-Frame compression?

Intra-Frame compression is indeed best associated with Spatial Compression. This method focuses on the data within a single frame or image to reduce file size without relying on other frames for context. By analyzing the pixels within that specific frame, spatial compression techniques can eliminate redundant information, leading to efficient storage and transmission.

For example, in a single image, if there are large areas of uniform color, spatial compression techniques can greatly reduce the amount of data needed to represent those areas. This is particularly valuable in video compression, where each frame can be compressed independently, allowing for easier retrieval and playback.

Understanding Intra-Frame compression in the context of spatial compression is crucial, particularly because it contrasts with other methods, such as Inter-Frame compression, which depends on data from preceding or subsequent frames for effective data reduction.
