## Description

DAIN is a video frame synthesis engine and AI video upsampling tool designed to increase video playback smoothness. It functions as a computer vision model that synthesizes intermediate frames between existing images to transform low frame rate video into high frame rate content.

The system utilizes depth-aware video frame interpolation to predict the motion of pixels between consecutive images. By analyzing spatial depth via depth maps, the tool generates new frames that account for occlusions and overlapping objects to create slow motion effects.

The framework incorporates optical flow integration and multi-scale feature extraction to capture both global motion and local details. It employs a bilateral solver for pixel refinement and is optimized through triplet-image training to improve synthesis accuracy.
