Light microscopy enlarges the viewing angle while decreasing the depth of focus. This leads
to mainly blurred images if the specimen being observed consists of significant height …

The technique utilized to retrieve spatial information from a sequence of images with varying
focus plane is termed as shape from focus (SFF). Traditional SFF techniques perform …

Shape from Focus (SFF) has been studied extensively in computer vision for 3D shape and
depth recovery. The first stage in SFF methods is to compute the focus value of every pixel …

The application of imaging techniques in plant and agricultural sciences had previously
been confined to images obtained through remote sensing techniques. Technological …

Three‐dimensional shape recovery is an important issue in the field of computer vision.
Shape from Focus (SFF) is one of the passive techniques that uses focus information to …

Rough surfaces such as metal additive manufactured surfaces are quite challenging for
measurement. Artifacts caused by irregular and difficult-to-measure geometries are …

The increasing space debris poses a great threat to in-orbit spacecraft and satellites,
because its hypervelocity impact can bring about fatal mechanical and electrical damage to …

We report a novel feature-matching method for side-scan sonar images. The method uses
nonlinear diffusion filtering to build a nonlinear scale space. The noise-reduction …

Quantitative tracking of rapidly moving micron-scale objects remains an elusive challenge in
microscopy due to low signal-to-noise. This paper describes a novel method for tracking …

Edge extraction from high spatial resolution (HSR) remotely sensed images is one of the
essential tasks for image segmentation and object identification. We present an optimal …
