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. Particle mode 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. Check button PTV - Checked for simulating low-image-density PIV recording for particle image tracking. |
