Optimal Gabor filter design for texture segmentation

چکیده

Texture segmentation involves accurately partitioning an image into differently textured regions. It requires simultaneous measurements in both the spatial and the spatial-frequency domains. Gabor filters are well recognized in the recent past as a joint spatial/spatial-frequency representation of textures. Daugman [16] has shown that Gabor filters have optimal joint localization in both the spatial and the spatial-frequency domains. In addition, they are bandpass filters, which are inspired by a multi-channel filtering theory for processing visual information in the early stages of the human visual system [17, 18].

Classification of Endometrial Images for Aiding the Diagnosis of Hyperplasia Using Logarithmic Gabor Wavelet

  Introduction: The process of discriminating among benign and malignant hyperplasia begun with subjective methods using light microscopy and is now being continued with computerized morphometrical analysis requiring some features. One of the main features called Volume Percentage of Stroma (VPS) is obtained by calculating the percentage of stroma texture. Currently, this feature is calculated ...

The Design of Multiple Gabor Filters for Segmenting Multiple Textures

Gabor filters have been successfully employed in texture segmentation problems, yet a general multi-filter multi-texture Gabor filter design procedure has not been offered. To this end, we first present a multichannel paradigm that provides a mathematical framework for the design of the filters. The paradigm establishes relationships between the predicted texture-segmentation error, the power s...

Optimal Gabor filters for texture segmentation

Texture segmentation involves subdividing an image into differently textured regions. Many texture segmentation schemes are based on a filter-bank model, where the filters, called Gabor filters, are derived from Gabor elementary functions. The goal is to transform texture differences into detectable filter-output discontinuities at texture boundaries. By locating these discontinuities, one can ...

P14: Segmentation Brain Tumors of FMRI Images by Gabor Wavelet Transform and Fuzzy Clustering

Today, high mortality rates due to brain tumors require early diagnosis in the early stages to treat and reduce mortality. Therefore, the use of automatic methods will be very useful for accurate examination of tumors. In recent years, the use of FMRI images has been considered for clarity and high quality for the diagnosis of tumor and the exact location of the tumor. In this study, a complete...
