- Back to image processing

- New selections of object feature display and feature file save

- New color space conversions (RGB->YIQ)

- Cyclic HUE color buffer subtraction functions

- New versions of Watershed function

- New Distance function with Euclidian distance

- Labeling function

- New Skeleton functions with different algorithms: Rosenfeld, Hilditch

- Difference of Gaussian filtering in frequency domain

- Fourier transform for rectangular images

- System calibration in different units, for instance: km, m, cm, mm, in, ft

- Calibration units will be converted automatically

- Physical unit for color coded calibration bar: length, velocity, acceleration

- Real user defined names for variables in the MACRO program language

- Pre-compilation of the MACRO program for faster execution

- New split-screen frame grabbing function

- Output data can be transfered to other programs via the DDE interface

- The program can be controlled remotely by other programs

- Many functions have been translated for the fast TMS320C40 DSP processor

in real time. Two cameras in stereo arrangement are used for this task.

If the location of the cameras is not known, the system can determine

the necessary transformation matrices by using a known test object.

The object position can be output as 3D-point coordinates or as dis-

placement and rotation relative to a reference position, using different

rotation models, like "yaw, pitch, roll" for airplanes.

calibration is very high. Results of the 3D-position tracking module can

additionally be used for calibration, if the object in question is moving.

Additional functions include statistical estimates, like mean displacement

of a series of deflection images, standard deviation, and accuracy of the

arithmetic mean value. New functions for graphical display of the results

are color coded vector display and combined color coded surface and vector

display. For helicopter applications the variations in the angle of attack

of the blades can be determined.

the correlation results in an extended resolution and accuracy. New functions

include the calculation of vorticity fields, statistical calculations like

mean, standard deviation, accuracy estimation of the arithmetic mean, and

the turbulence field. New functions for color coded display of the velocity

or vorticity fields are implemented
