Lightspace: A natural domain for imaging and analysis.
This thesis demonstrates the value of lightspace image processing by detailing computer programs developed for high-quality, multiple flash studio imagery which uses only consumer grade digital imaging equipment and a single flash along with lightspace image processing to produce spectacular studio quality results.This thesis describes the benefits of working in a light-linear space for the purpose of image processing. Several consequences are explored and the benefits are explained. To transform images from pixels (referred to in this thesis as imagespace) to the light-linear space (termed lightspace), an important statistical structure, the superposigram, is introduced. The first purpose of the superposigram is to simply find the transformation into this light-linear space. Later, the superposigram is used to understand and model the noise present in an imaging system.Once the transformation of images has been made into lightspace, the thesis explores the potential of working in this space. One of the most important consequences is that of extended-dynamic range imaging and extended-dynamic range image processing, also termed super-tonal imaging. This thesis points out the benefits of working in this space, and solves the problem of how to handle the increased amount of data.Finally, the thesis utilizes lightspace file formats to explore the concept of camera resolution. A new pleasure of resolution, the Heisenberg-Gabor figure-of-merit is suggested. This single figure-of-merit is proposed to combat a growing perception that the measure of megapixels is a valid means of describing a camera"s resolution. The figure-of-merit proposed is a single number, which in essence, evaluates the modulation transfer function, and thus the resolution, of an imaging system.

Spectrogram. A spectrogram takes a series of FFTs and overlaps them to illustrate how the spectrum (frequency domain) changes with time. If vibration analysis is being done on a changing environment, a spectrogram can be a powerful tool to illustrate exactly how that spectrum of the vibration changes. PSD.

Image analysis Image analysis is a typical domain for which a high degree of abstraction from low-level methods is required, and where the semantic gap immediately affects the user. If image content is to be identified to understand the meaning of an image, the only available independent information is . The Fourier Transform for continuous signals is divided into two categories, one for signals that are periodic, and one for signals that are ic signals use a version of the Fourier Transform called the Fourier Series, and are discussed in the next Fourier Transform used with aperiodic signals is simply called the Fourier Transform.

QUALITATIVE ANALYSIS "Data analysis is the process of bringing order, structure and meaning to the mass of collected data. It is a messy, ambiguous, time-consuming, creative, and fascinating process. It does not proceed in a linear fashion; it is not neat.
Qualitative data analysis is a search for general statements about relationships among. In image enhancement, the goal is to accentuate certain image features for subsequent analysis or for image display . Examples include contrast and edge enhancement, pseudo-coloring, noise filtering, sharpening, and magnifying.
Image enhancement is useful in feature extraction, image analysis and an image. Time Series Analysis and Its Applications presents a balanced and comprehensive treatment of both time and frequency domain methods with accompanying theory.
Numerous examples using nontrivial data illustrate solutions to problems such as discovering natural and anthropogenic climate change, evaluating pain perception experiments using functional magnetic resonance imaging, and monitoring 3/5(15).
