New PDF release: Application of Chaos and Fractals to Computer Vision

By Michael E. Farmer

This publication offers an intensive research of the appliance of chaos conception and fractal research to machine imaginative and prescient. the sphere of chaos thought has been studied in dynamical actual platforms, and has been very profitable in supplying computational types for terribly advanced difficulties starting from climate platforms to neural pathway sign propagation. machine imaginative and prescient researchers have derived motivation for his or her algorithms from biology and physics for a few years as witnessed through the optical movement set of rules, the oscillator version underlying graphical cuts and naturally neural networks. those algorithms are very worthy for a wide diversity of desktop imaginative and prescient difficulties like movement segmentation, texture research and alter detection.
The contents of this e-book comprise chapters in organic imaginative and prescient structures, foundations of chaos and fractals, habit of pictures and snapshot sequences in part area, mathematical measures for interpreting part house, functions to pre-attentive imaginative and prescient and purposes to post-attentive vision.
This booklet is meant for graduate scholars, higher department undergraduates, researchers and practitioners in snapshot processing and laptop imaginative and prescient. The readers will advance an excellent figuring out of the techniques of chaos idea and their software to machine imaginative and prescient. Readers may be brought to a brand new frame of mind approximately desktop imaginative and prescient difficulties from the viewpoint of advanced dynamical platforms. This new method will offer them a deeper knowing of a few of the phenomena found in complicated snapshot scenes.

Example text

Because of these efforts in explaining biological neural systems through chaotic dynamics it was quite natural that researchers began exploring adding chaos theory to artificial neural networks and this has been a common approach for enhancing neural network algorithmic performance. Chaos theory to date, however, has been focused predominantly on applications to neural networks in the computer vision community. Some researchers have applied chaos theory to peripheral tasks such as image compression, but it has not found a home in the traditional computer vision tasks such as segmentation, image registration, or feature extraction.

This implies that for every amplitude pixel in the image there was no change, as was expected, since we compared the image with itself. Fig. 9 (c) provides a zoom of a single phase plot further clarifying the vertical phase plot. We will utilize the idea of a vertical line in phase space representing no change when we analyze the effects of global illumination changes on an image in the Chapter 4. We will see that global illumination merely changes the slope of this vertical line which implies phase space is a very natural representation for providing illumination immunity.

8. Since we will be relying on the space-filling nature of interesting image phenomena we need to define the phase plot resulting from the baseline analysis. Fig. 9 (a) provides an example of a typical street scene which will be used to compute the phase plots in Fig. 9 (b). In Fig. 9 (b) the phase plots for every grid cell of the image demonstrates a simple vertical line. This implies that for every amplitude pixel in the image there was no change, as was expected, since we compared the image with itself.
