Thanks guys, I'm I will find a solution now from your inputs. Andries

Hi, I have made a program that transforms the R,G,B values of an image into H,S and I arrays. I use a 3D surface graph to visualize the hue is a 3D manner. The problem is: When a picture has a resolution of about 320 X 240 the 3D surface graph is resonable quick but when the image is too large the 3D surface graph becomes unreasenable slow. I managed to downsize the image resolution. In combination with a zoom function I'm able to see all the pixel data if necessary. But then again when the images become too large (>1280*1024) the methode it self becomes unreasenable slow. How can I down size the image data. Is there mayby a dll file with an example available? Andries PS. I use Labview 7.0

Thanks for your reaction. Thats indeed a good way to find the other end of the peak. I didn't thought of that. But I need a continuous run. If its possible to isolate a single movement from a much larger array, I can perform all kinds calculations and run some filters on every movement to suppress the drift. Andries

Hello, I'm tring to use an bluetooth accelerator sensor to determine movement. An accelerator sensor always has the problem of drift. Drift means that the speed (1 time intergration of acceleration) doesn't return to 0 after acceleration and decceleration. This causes a small error in the speed but a enormous in the movement. In my case the accelerator sensor is used in combination with a robot. After every movement the robot stops for a few seconds. This time windows can be used to recalibrate the sensor. I want to add up all the positive (acceleration) and the negative (decceleration) sensor output values and make them equal by multipling the output values by a small (depends on the difference between the two) correction factor. My problem: I need to determine from which sample until which sample the movement was. Like I sad above the acceleration is 0 if the robot stops. I managed to determine the beginning of the piek but the end appear to be difficult. Can somebody help me with this? Thanks.

QUOTE(Rimmergogo @ Mar 1 2007, 01:27 PM) I fixed the problem already by substracting 4294967296 from the horizontal value wen it is above 2000. but still the bug remains unclarified.

Hallo, I want to make a labview program that can store the coordinations / route of the mouse, but only went the mouse is in a xy-plot area. But now I have run into a strange error. (I have attached my labview program so that you can see for your self). When the horizantal coordination are lower then the coordinations of the the xy graph the calculated new mouse horizontal coordination is rised by 4294967296. There are two funny things: this number is 2 times the max of an I32 and if I replace the xy-graph coordinations by an constant there is no error. Does anybody know what this error is about. thanks, Andries
