Being a computer science background student I choose the computer vision. 
Computer vision is a field of artificial intelligence that focuses on enabling machines to interpret and understand visual data from the world, much like humans do. By using deep learning algorithms, computer vision systems can analyze and extract meaningful information from images and videos, such as recognizing objects, detecting faces, and tracking motion. 
This technology powers a wide range of applications, from autonomous vehicles and facial recognition to medical imaging and quality control in manufacturing. With the ability to process visual data at scale and in real time, computer vision is revolutionizing industries and making our everyday technologies smarter and more easy.
