Technical Knowledge & Skills

• 6. What is the difference between image enhancement and image restoration?
  Answer: Image enhancement is the process of improving the quality or visual appearance of an image, while image restoration is the process of recovering the original image from a degraded or corrupted version.
• 7. How do you handle noise in an image?
  Answer: In image processing, noise refers to random variations in pixel values that can affect the quality of an image. To handle noise, I usually use filters such as median filter or Gaussian filter, or apply techniques such as noise reduction algorithms.
• 8. Can you explain the concept of image segmentation?
  Answer: Image segmentation is the process of dividing an image into multiple segments or regions based on certain characteristics, such as color, texture, or intensity. It allows for a more detailed analysis of specific areas in an image.
• 9. How would you handle images with complex backgrounds for object detection?
  Answer: I would use techniques such as background subtraction or image thresholding to remove the background from the image. This would make it easier to isolate and detect objects in the foreground.
• 10. Can you explain the concept of homography in image processing?
  Answer: Homography is a transformation that maps points in one image onto corresponding points in another image. It is commonly used in image registration, image matching, and image stitching.

Behavioral & Situational Questions

• 11. How do you handle tight deadlines and pressure in your work?
  Answer: I prioritize tasks and plan my time effectively to ensure that I can meet deadlines without compromising the quality of my work. I also communicate any potential challenges to my team and find ways to work together to overcome them.
• 12. How would you handle a situation where a client is unhappy with the results of your image processing project?
  Answer: I would first try to understand the client's concerns and address them by providing a detailed explanation of the project and how we arrived at the results. If necessary, I would make adjustments or suggest alternative solutions to ensure the client's satisfaction.
• 13. Can you give an example of a time when you encountered a technical issue in a project and how you resolved it?
  Answer: In one project, I encountered an issue with image quality due to lighting conditions. I researched different techniques and found a solution using image enhancement algorithms to improve the quality of the images and achieve the desired results.
• 14. How do you make sure that your image processing techniques are accurate and reliable?
  Answer: I conduct thorough testing and validation of my algorithms using different datasets and images to ensure their accuracy. I also use statistical analysis and compare results with existing approaches to confirm the reliability of my techniques.
• 15. Can you describe a time when you had to make a difficult decision in a project?
  Answer: In one project, we encountered an unforeseen technical issue that required a change in the project plan. I had to make a decision whether to stick with the original plan and risk quality issues or adjust the plan to ensure high-quality results. After consulting with my team, we decided to adjust the plan and were able to successfully complete the project with quality results.

Cultural Fit Questions

• 16. How do you keep your skills and knowledge up-to-date?
  Answer: I believe it is important to continuously learn and adapt in the fast-paced field of image processing. I regularly attend workshops and seminars, and also engage in self-learning by reading industry publications and experimenting with new techniques on my own.
• 17. How do you approach working in a team?
  Answer: I am a strong believer in collaboration and open communication. I listen to others' ideas and perspectives, share my own thoughts and contribute to discussions, and support my team members to achieve our common goals.
• 18. How do you handle constructive criticism?
  Answer: I see constructive criticism as an opportunity to improve and learn from others. I listen carefully, ask questions to gain a better understanding, and then take the feedback into consideration to make necessary changes.
