Aspect Ratio

Aspect ratio, the ratio of width to height in an image or video, is a crucial factor influencing the performance of various computer vision tasks. Current research focuses on mitigating the negative impacts of varying aspect ratios, particularly in object detection, image recognition, and video processing, employing techniques like adaptive model architectures (e.g., Vision Transformers with flexible input handling) and data augmentation strategies to improve robustness. These advancements are significant for enhancing the accuracy and efficiency of applications ranging from driver drowsiness detection to automated medical image analysis and high-resolution video retargeting.
