2. Which of the following process helps in Image enhancement?a) Digital Image Processingb) Analog Image Processingc) Both a and bd) None of the above

To determine which process helps in image enhancement, let's analyze the options:

1. Digital Image Processing: This involves the manipulation of images using digital techniques, which allows for various enhancements such as adjusting brightness, contrast, filtering, etc.

2. Analog Image Processing: This refers to the processing of images in their analog form (e.g., using film or non-digital techniques). While it can involve some form of enhancement, it is generally less flexible and powerful compared to digital methods.

3. Both a and b: This option suggests that both processes contribute to image enhancement.

4. None of the above: This states that neither process aids in image enhancement.

Conclusion:

Since digital image processing is specifically designed for manipulating and enhancing images, and it is generally more effective than analog image processing for this purpose, the best choice is:

a) Digital Image Processing

Final Answer

a) Digital Image Processing
