Image processing for consumer electronics - £30 GBP

In this book we explain how image are captured, processed and compressed in consumer electronics applications.

Images

The quality of images is a key factor for consumer products. Perceived image quality depends on a lot of factors, many based on the psychology of seeing but implemented in highly technical ways. In this book we explain how images and video are captured, processed, compressed, decompressed and finally rendered for the viewer in consumer electronics applications. We take a practical approach that clarifies the background and purpose of the technical processes as well as explaining them in depth.

Basics of digital images including context and purpose, conventions and the image capture chain.

• Pictures
• Scenes, frames and images
• Field of view
• Focus of attention

Image transforms

We introduce transforms in image processing, including the concepts of spatial frequency and the wavelet transform.

• Spatial frequency
• Fourier Transforms
• 2D transforms
• Edges, lines and patterns
• Image filtering
• Discrete Cosine Transform
• Wavelets

Image sampling

How images are sampled and the effect this has.

• Raster scan and image sampling
• Aliasing and reconstruction
• Video time sampling
• Frames, fields and interlace

Enhancement & correction

We outline important techniques for enhancement and correction of images, including geometric distortion as well as colour balance.

• Sharpening and de-blurring
• Auto focus
• Scaling and interpolation
• Edge detection and enhancement
• Histogram modification
• Color balance
• De-interlacing and pull-down

Color and vision

Color, vision and the human dimension: color spaces and perceptive coding: sampling colour images.

• Luminance and colour
• Resolution and sensitivity
• Colour spaces: RGB and YUV
• Colour sampling schemes
• Colour leakage and aliasing
