Advanced EBSD Pattern Interpretation through Iterative Post-Processing

Image Post-Processing and Interpretation

Image post-processing is defined as the process of integrating a series of axial images into a form that is often easier to interpret than the sections themselves. The source transverse section is a fundamental image for interpretation. However, because of the complexity of coronary anatomy, interpreters must review coronary CT angiography interactively on workstations capable of 3-dimensional ...

A New Microstructural Imaging Approach through EBSD Pattern Region of Interest Analysis

The requirements of a highly tilted sample and a well-polished surface for optimal EBSD pattern collection can make traditional SEM imaging challenging. With a tilted sample, SEM SE and BSE detectors are often in non-optimal positions for electron detection. For many materials, the polished surfaces produce weak contrast with SE imaging. Traditionally placed BSE detectors must be used with care...

Reducing the Complexity of Iterative Post-processing of Video

We propose a method of reducing the computational complexity of iterative video post-processing algorithms that make use of the convex quantization constraint set. Rather than constraining all DCT coefficients in a block, this method constrains only a subset of a block’s DCT coefficients, and hence eliminates the need to evaluate all coefficients.

Errors, artifacts, and improvements in EBSD processing and mapping.

Electron back scatter diffraction (EBSD) mapping and indexing has rapidly come into widespread use. However, inadequate attention has been paid to the details of the method. Many of the algorithms in current use were chosen because they were the first ones that were found to work, rather than because they were optimum. Results of systematic study are presented. It is shown that more than one me...
