Objectives What is Image Restoration?. Causes of Image Degradation. Types of Noise and Their Characteristics. Image Restoration Techniques. Applications of Digital Image Processing.
What Is image restortion Image Restoration is a process in which techniques are used to recover an original image that has been degraded by various factors. Various factors may include sensor noise,motion blur, defocus,transmission errors. Image Restoration is used in NUMEROUS fields including medical imaging,satellite imagery,digital photography. Almost Similar to Image Enhancement,but more objective.
What Is image restortion
Causes of image degradation Motion Blur : Movement during image capture can result in blurred images, particularly in low shutter speed conditions or when capturing fast-moving subjects. Poor Focus : Incorrect focus settings or focusing errors can lead to blurry images or misfocused areas. . Image degradation can occur due to various factors, both during capture and processing. Here are some common causes : Sensor Noise : Noise generated by the camera sensor or electronic components can degrade image quality, especially in low-light conditions.
Example of image degradation Motion Blur Poor Focus
types of noise and their characteristics NOISE REFERS TO ANY UNWANTED OR IRRELEVANT DISTURBANCE THAT INTERFERES WITH THE CLARITY OR FIDELITY OF A DESIRED SIGNAL,HERE ARE SOME TYPE OF NOISES: Quantization Noise: Imagine you have a digital signal that looks like a staircase, with flat steps instead of a smooth curve. These flat steps are what we call quantization noise. salt and Pepper Noise: Imagine you have a picture that looks like it has random black and white specks all over it, like salt and pepper. These specks are what we call salt and pepper noise. It's often caused by errors in the image acquisition process, and can make it difficult to see the actual image
Example Of Noises Salt and pepper noise Quantization noise

Invention design process Talk about the design process Did your first build work, or did you have to change your ideas? Why? Did you have to change the materials you used as you tested your invention? Why? <Insert pictures or drawings of your invention design/building process> *you can insert a new slide for these pictures/drawings if you need to!
My Invention in Use! Talk about how people reacted to your invention Did it solve the problem/need you identified? Did it work as planned? Did it help whom it needed to help? <Insert pictures or drawings of your invention being used, with a description entered here> *you can insert a new slide for these pictures/drawings if you need to! <Insert pictures or drawings of your invention being used, with a description entered here> *you can insert a new slide for these pictures/drawings if you need to! <Insert pictures or drawings of your invention being used, with a description entered here> *you can insert a new slide for these pictures/drawings if you need to!
