This Notion document contains a comprehensive presentation on image processing, which covers a wide range of topics related to digital images. The presentation begins with an explanation of the fundamental concepts of digital images, including sampling and quantization, which are essential for understanding the basic characteristics of digital images. It then moves on to discuss image properties such as bit depth and dimensions, which play a significant role in determining the range of colors that can be represented in an image, as well as its overall appearance and quality.

The presentation also delves into various image enhancement techniques that can be used to improve the quality and appearance of digital images. These techniques include linear and contrast stretching, histogram processing, and spatial domain operations such as single pixel and neighborhood operations, geometric transformations, and padding. The presentation provides detailed explanations of each technique, along with examples and illustrations to help users understand their practical applications.

Additionally, the presentation provides a list of resources for further reading and learning, including a comprehensive guide to image processing, online tutorials, and software tools that can be used for image processing. The document is owned by Lucinda Gaines, who has expertise in geo-intelligence, remote sensing, and machine learning, which makes the presentation a valuable resource for anyone interested in these fields.

Overall, this Notion document provides a thorough and informative presentation on image processing that is suitable for both beginners and advanced users. It covers a wide range of topics related to digital images, and provides practical examples and resources that can be used to enhance the quality and appearance of digital images.

What is an Image?

A digital image is made up of a 2-dimensional grid, where each cell of the grid represents a specific part of the image and carries a value that corresponds to that part of the image's discrete signal.

Bit depth refers to the number of bits used to represent each color channel in an image. In digital images, each pixel is made up of multiple color channels, such as red, green, and blue. The bit depth determines the number of possible values that each channel can have, which in turn affects the range of colors that can be represented in the image. For example, an 8-bit image has 256 possible values for each color channel, while a 16-bit image has 65,536 possible values. A higher bit depth generally results in more accurate and detailed color representation, but also requires more storage space and processing power.
