Texture Classification Using Transform Analysis, Mary Habib
Texture Classification Using Transform Analysis, Mary Habib
Archived Theses and Dissertations
The work presented in this thesis deals with the application of spectral methods for texture classification. The aim of the present work is to introduce a hybrid methodology for texture classification based on a spatial domain global pre-classifier together with a spectral classifier that utilizes multiresolution transform analysis. The reason for developing a spatial pre-classifier is that many discriminating features of textures are present in the spatial domain of the texture. Of these, global features such as intensity histograms and entropies can still add significant information to the texture classification process. The pre-classifier uses texture intensity histograms to derive histogram …

On-Line Signature Verification Using Global Features, Akrum Mamdouh Shawky
Archived Theses and Dissertations
The work presented in this thesis deals with the development of an on-line Handwritten Signature Verification methodology based on certain Global features that represent the entire signature as a whole. The aim of the research is to come up with an efficient "acceptance/rejection" mechanism that can be used to verify the authenticity of a certain signature. Global features are less expensive to compute than local features, they provide fast verification, and should provide accurate verification results. After identifying the entire global set of attributes that are to be investigated, Cramer's v-statistics and information-theoretic entropy measures of association were used in …
Optimization Of Receptive Fields For Mlp Networks With Ensemble Encoding, Deena Osama Hassan
Optimization Of Receptive Fields For Mlp Networks With Ensemble Encoding, Deena Osama Hassan
Archived Theses and Dissertations
Ensemble encoding is a biologically-motivated, distributed data representation scheme for MLP networks. Multiple overlapping receptive fields are used to enhance locality of representation. The number, form, and placement of receptive fields have a great impact on performance. This thesis presents four heuristics, two based on descriptive statistics, and two based on clustering, for optimizing receptive field configuration, and compares their performance on four benchmark data sets. The two statistical approaches are based on the mean and median properties of the data set. The two clustering methods are the c-means and fuzzy c-means clustering. The four data sets used are well-known …
Synthesis And Optimization Of Digital Systems For Low Power At Logic Level Of Abstraction, Ihab Mostafa Amin Amer
Synthesis And Optimization Of Digital Systems For Low Power At Logic Level Of Abstraction, Ihab Mostafa Amin Amer
Archived Theses and Dissertations
In this thesis we tackle one of the most important fields of research, which is reducing power consumption in digital systems. The importance of this field comes from the fact that nowadays, several digital devices are intensively used in our daily life. Thus, minimizing their power consumption is a common demand from the technological as well as the economical point of view. Some basic definitions in the low power design field are introduced. Besides, a preview of different efforts that were exerted in the field of reducing power consumption of digital systems at various levels of abstraction is presented. A …
