I need to develop a software to detect the defect of LCD (phone) screen. Is matlab a good tool to develop the software?
I need to detect if the lcd screen has stuck pixels. and what color does the stuck pixel is. The image is captured by a camera.

Hi Yt,
MATLAB can be a good tool for developing a prototype or proof-of-concept software for detecting defects in LCD screens, such as stuck pixels. It offers a range of image processing and computer vision capabilities that can be useful for this task. Here are some considerations and steps to help you get started:
Why Use MATLAB?
  1. Image Processing Toolbox: MATLAB's Image Processing Toolbox provides a wide range of functions for image analysis, enhancement, and manipulation, which are essential for detecting stuck pixels.
  2. Computer Vision Toolbox: This toolbox offers algorithms for feature detection, extraction, and image processing, which can be leveraged to analyze the captured images of the LCD screen.
  3. Rapid Prototyping: MATLAB allows for quick prototyping and testing of algorithms, which can be beneficial in the early stages of development.
  4. Visualization: MATLAB provides powerful tools for visualizing data and results, making it easier to interpret the outcomes of your image analysis.
Hope it helps.

Yes, MATLAB is a great tool for developing image processing apps. It's easy to program in and has a great library of functions you can call upon, plus it has an active and responsive user community.
For what it's worth, I'm attaching my LCD 7 segment display demo. It does OCR and does not specifically tackle your problem.
