Topic 1E - Digital Image Processing

What is the purpose of digital image processing?

• To perform image processing on digital images

• To delete digital images

• To create digital images from scratch

• To print digital images

What are some examples of image anomalies?

• Blur and color balancing

• Glare from the sunlight and processing chip malfunction

• Image enhancement and image compression

• Geometric restoration and image manipulation

Which technique is used to reduce the storage requirements of digital images?

• Image Enhancement

• Image Restoration

• Image Manipulation

• Image Compression

What is the difference between lossless and lossy image compression?

• Lossless retains image quality, while lossy removes imperceptible information

• Lossless removes image quality, while lossy retains imperceptible information

• Lossless and lossy have the same compression method

• Lossless and lossy are not related to image compression

Which file format uses lossless compression?

• Joint Photographic Experts Group (JPEG)

• Graphical Interchange Format (GIF)

• Tagged Image File Format (TIFF)

• Portable Network Graphics (PNG)

What is the purpose of image restoration?

• To manipulate images using computer tools

• To compress image data files

• To enhance the visual appearance of an image

• To totally remove the effects of image degradation

What is the goal of geometric restoration?

• To produce an artificial image using computer tools

• To remove image blur imposed by defocus and motion blur

• To adjust the color components of an image

• To restore the proper spatial relationships among objects in the scene

What is digital image manipulation?

• Removing image blur imposed by known causes

• Enhancing the visual appearance of an image

• Adjusting the color components of an image

• Altering an image using computer program tools to produce an artificial image

Which image compression method allows you to control the level of compression?

• TIFF (Tagged Image File Format)

• PNG (Portable Network Graphics)

• GIF (Graphical Interchange Format)

• JPEG (Joint Photographic Experts Group)
