PLSR-based surface damaged layer depth determination of sawed natural diamond

Layer-Based Surface Editing

By decomposing a surface into a sequence of levels with different frequency bands, users can manipulate and modify specified levels without affecting others. This idea has been extensively explored with various multi-resolution techniques [KVS99, GSS99]. However, encoding details as local frame displacements, as widely done in multi-resolution techniques, causes two major problems. First, the i...

Induction Thermography for Surface Crack Detection and Depth Determination

In the last few years, induction thermography has been established as a non-destructive testing method for localizing surface cracks in metals. The sample to be inspected is heated with a short induced electrical current pulse, and the infrared camera records—during and after the heating pulse—the temperature distribution at the surface. Transforming the temporal temperature development for eac...

Determination of the Surface Boundary Layer Using a Quadrotor

Image Parallax Based Modeling of Depth-Layer Architecture

We present a method to generate a textured 3D model of architecture with a structure of multiple floors and depth layers from image collections. Images are usually used to reconstruct 3D point cloud or analyze facade structure. However, it is still a challenging problem to deal with architecture with depth-layer structure. For example, planar walls and curved roofs appear alternately, front and...

Effect of Pile Foundation on Natural Frequency of Soil Layer

Free vibration of soil often occurs during earthquakes. Since the vibration caused by earthquake does not have (steady state harmonic vibration) continuity, the alluvium vibrates with its natural frequency between two natural seismic waves. This study evaluates the effect of piles on the period of free vibration of a soil layer using numerical method. In the first stage, using analytical equati...
