Focus Measure

Focus measure research aims to automatically determine the optimal focus point in an image or video sequence, crucial for various applications from photography to robotics. Current research explores diverse approaches, including deep learning models (like convolutional neural networks) that analyze focal stacks or event data to estimate depth and focus, and algorithms leveraging gradient information or event camera polarities for improved speed and robustness. These advancements are improving the accuracy and efficiency of autofocus in diverse imaging modalities, including thermal and hyperspectral imaging, impacting fields such as medical imaging, autonomous navigation, and computer vision.
