Random particle distribution
Number/[32x32 pix] - Number of particle images in a 32x32-pixel window;
Max. diameter [pix] - Maximal diameter of the particle images;
Min. diameter [pix] - Minimal diameter of the particle images;
Max. brightness - Maximal brightness (0-255) of the particle images;
Min. brightness - Minimal brightness (0-255) of the particle images;
Extended view (%) - Field of view is extended with given percentage to include particles that come into and go out of the frame.
Ellipse particle cross-section
Ry / Rx - Radius ratio of the ellipse cross-section of particle images;
Orientation - Orientation angle of the main axis of the ellipse cross-section.
Quick - Gray value determined by the Gaussian function value at the center point of each pixel;
Fine - Gray value determined by the integral of the Gaussian function in each pixel unit. A 9-point discrete integration scheme is applied.
PTV - Checked for simulating low-image-density PIV recording for particle image tracking.
