Automatic Image Segmentation Optimized by Bilateral Filtering
The object-based methodology is one of the most commonly used strategies for processing high spatial resolution images. A prerequisite to object-based image analysis is image segmentation, which is normally defined as the subdivisión of an image into separated regions. This study proposes a new image segmentation methodology based on a self-calibrating multi-band región growing approach. Two mu...
متن کاملRecursive Bilateral Filtering
This paper proposes a recursive implementation of the bilateral filter. Unlike previous methods, this implementation yields an bilateral filter whose computational complexity is linear in both input size and dimensionality. The proposed implementation demonstrates that the bilateral filter can be as efficient as the recent edge-preserving filtering methods, especially for highdimensional images...
متن کاملStructure-oriented bilateral filtering
Bilateral filtering is widely used to enhance photographic images, but in most implementations is poorly suited to seismic images. A bilateral filter consists of two filter kernels. By replacing one of those kernels with a smoothing filter that conforms to image structures, we obtain a bilateral filter suitable for seismic image processing. Examples and comparison with conventional edge-preserv...
متن کاملMorphological Bilateral Filtering
A current challenging topic in mathematical morphology is the construction of locally adaptive operators; i.e., structuring functions are dependent on the input image itself at each position. Development of spatially-variant filtering is well established in the theory and practice of Gaussian filtering. The aim of the first part of the paper is to study how to generalize these convolutionbased ...
متن کاملShot Noise Adaptive Bilateral Filtering
The bilateral filter [1, 2] has an important place in image denoising. It smooths images while preserving edges using means of nonlinear combination of local pixels values. The method formulation and implementation are simple. However the set of the bilateral filter parameters has an important influence on its filtering behavior. They have to be chosen considering the user application. In the c...
