Image and video processing are foundational research areas in computer vision. They involve techniques for acquiring, manipulating, and analyzing visual data. Some of the major research topics in this area include:
- Image enhancement: Developing algorithms to improve the quality of images, such as denoising, contrast enhancement, and super-resolution.
- Image segmentation: Dividing an image into multiple segments or regions based on certain criteria, such as color, texture, or motion.
- Object detection: Identifying and locating objects within an image or video frame.
- Tracking: Tracking the movement of objects over time, which is crucial for video analysis and understanding.
2、3D Vision
3D vision focuses on extracting and understanding the 3D structure of the world from 2D images or video sequences. This research direction has several key areas:
- Stereo vision: Using two or more cameras to capture images of the same scene from different viewpoints and estimating the depth information between them.
- Structure from motion (SfM): Estimating the 3D structure of a scene by analyzing the motion of a camera or cameras over time.
- 3D reconstruction: Creating a detailed 3D model of a scene or object from multiple images or video frames.
3、Deep Learning in Computer Vision
Deep learning has revolutionized the field of computer vision, enabling the development of highly accurate and efficient algorithms. Some of the research directions in deep learning for computer vision include:
- Convolutional neural networks (CNNs): Developing and optimizing CNN architectures for various computer vision tasks, such as image classification, object detection, and segmentation.
