Computer Vision Hardware Engineer Interview Questions
Sample answer to the question
Image processing is the manipulation of digital images using various techniques to enhance or extract meaningful information. Signal processing involves analyzing and modifying signals to extract useful information or to remove noise. Machine learning is a field of study that focuses on the development of algorithms that can learn from and make predictions or decisions based on data. I have a strong understanding of these principles and have applied them in my previous work. For example, I worked on a project where we developed an image recognition system using deep learning algorithms. We pre-processed the images to enhance the features and then used signal processing techniques to extract relevant information. The pre-processed images were then fed into a machine learning model that was trained on a large dataset. The model was able to accurately classify the images with high accuracy. Overall, I believe my knowledge and experience in image processing, signal processing, and machine learning principles make me well-suited for this role.
