Background Removal from Images Using Erosion and Contour Elimination

Background removal through erosion and contour elimination represents a fundamental image processing technique particularly suitable for MATLAB programming beginners. These operations provide hands-on experience in understanding image processing program development while deepening comprehension of background removal methodologies. The process introduces beginners to key MATLAB functions such as imerode() for morphological erosion and bwperim() for contour detection. Through iterative implementation of thresholding, morphological operations, and logical masking, learners gain proficiency in combining multiple image processing techniques. Practical experimentation helps develop essential programming skills and problem-solving approaches in digital image manipulation. This foundational exercise not only teaches practical image processing techniques but also cultivates systematic programming thinking and analytical capabilities through real-world implementation challenges.
