Fundamentals - Image and Imaging

[bellabf]

Hello everyone,
This is the revised outline for the Image and Imaging chapter.

1. What is an image? [image.mdx]: taken by me and @seshu-pavan

• Definition of Image
• Difference between Image and Video
• Image-specific challenges (i.e.comparing images to other types of data)

2. Fundamentals of Imaging and its technical aspects of images [imaging.mdx] taken by @krmdel

• Image formation: Bayer Grid / Filter, Digital Image Sensing, Color space representations
• Image representation: Type of image representations, RGB's, image as the matrix,
• Output of images: Image resolution, Pixel/Voxel, Dimensions Channels, Dynamic range, Bit depth, File Compression, Image formats, Metadata
• enhancement and restoration

3. How we imaged everything/When in doubt, image it. [extension-image.mdx] taken by me

• Challenges in imaging real-life
• Imaging everything (how we extend sensors to make images from things that are not usually thought of as images)
• Perspective on what we obtained from this and its impact on us (i.e. we have imaged outer space and electrons; we have an MRI machine capable of imaging inside of us without ever touching 🤯)
• Example(s) of how image-acquired characteristics of images come from what types of sensors they record, challenges/difficulties in computer vision change according to the image/data, not all data is RGB

4. Preprocessing for Computer Vision. [examples-preprocess.mdx] taken by @mfidabel and @krmdel

• pre-processing techniques to compare images types (i.e. histograms, thresholds techniques, edge detection look like in image coming from different conditions
• common operations before training (downsampling and data augmentation).

Our biggest concern was the possible overlap of our content with the “Feature Detection/Feature Extraction chapter” content, especially regarding image transformations, filters, and convolution. We opt to left it out, considering that the proposed outline for Feature Detection. and to stay in touch with their team.

Taken in this case, just means we were the first people to start the chapter and/or we are focus on it.
There are a lot of active discussions between members to make the content more cohesive and easy to follow.

Let us know what you think!

Great! Broadly looks very nice. ✨ 😄

I think it's good to leave out for now, if it needs to be added we can do so in a later update
