  1. High Dynamic Range (HDR) Imaging:
    a. Dynamic Range: We’ll explore the concept of dynamic range in imaging, discussing the limitations of standard image formats and the need for capturing and processing high dynamic range scenes.
    b. Tone Mapping: We’ll delve into tone mapping techniques used to compress the dynamic range of HDR images, allowing them to be displayed on standard monitors while preserving visual details.
  2. Color Space Extensions:
    a. Wide Gamut Color Spaces: We’ll discuss wide gamut color spaces like Adobe RGB and DCI-P3, which offer a broader range of colors compared to standard RGB color spaces, and their significance in professional photography and digital cinema.
    b. HDR Color Spaces: We’ll explore color spaces designed specifically for HDR content, such as Rec.2020 and ACEScg, which can represent a wider color gamut and higher dynamic range.
  3. Color Appearance Models:
    a. CIECAM02: We’ll introduce the CIECAM02 color appearance model, which takes into account various factors like illumination conditions and surrounding colors to simulate human color perception accurately.
    b. CAM16: We’ll discuss the advancements made with the CAM16 color appearance model, which offers improved accuracy in predicting color appearance under different viewing conditions.
  4. Advanced Color Manipulation Techniques:
    a. Color Transfer: We’ll explore color transfer techniques that aim to match the color characteristics of one image to another, allowing for artistic stylization and color harmonization.
    b. Colorization: We’ll discuss colorization methods that add color to grayscale images, including both automatic and user-guided approaches, and their applications in historical image restoration and artistic rendering.
    c. Image Relighting: We’ll delve into image relighting techniques that enable the manipulation of lighting conditions in an image, offering creative control over the illumination and mood of a scene.
  5. Computational Photography and Imaging:
    a. Image Deblurring: We’ll explore advanced deblurring algorithms that can recover sharp images from blurry or motion-blurred photographs, leveraging sophisticated mathematical models and machine learning techniques.
    b. Super-Resolution: We’ll discuss super-resolution techniques that enhance image resolution, allowing for the generation of high-resolution images from low-resolution counterparts through sophisticated algorithms.
    c. Image Inpainting: We’ll touch upon image inpainting methods that can intelligently fill in missing or damaged regions of an image, leveraging surrounding information and context.
