[BLACKBOX] Real time & garbage collection

----boundary-LibPST-iamunique-1745745614_-_- Content-type: text/plain Folks, I have produced a product for a company (surprisingly in Switzerland) that smooths the position of detected eyes from a webcam. I show two sets of eyes: the original, as given to me by a face detection dll and my smoothed version of the original. Every once in a while the images seem to hang (1 second) and then start to move again. The author of the face dll claims he doesn't see that effect. So, I am wondering whether the BlackBox garbage collector is kicking in. This is just a hypothesis and want to explore it with the rest of you. How can I determine (be notified) when the garbage collector starts and stops? Is it possible to inhibit the garbage collector? That is, can I create a safe region of code where the garbage collector will not be called? I don't believe I am doing NEW during the eye smoothing operations but then again I may have over looked a place or places in my code where I do. How can I determine whether NEW is being called while the code is running? By pressing ctrl-alt-del I can watch the total amount of memory that my process is using and it seems to be fairly constant so if I am calling NEW it is not of any great amount. Does the garbage collector mark and sweep through all of allocated memory or just memory that has been added since the last time it was called (just curious)? Do you have a suggestions? Any tools in BlackBox that could answer some of these questions? -Doug Danforth ---- To unsubscribe, send a message with body "SIGNOFF BLACKBOX" to LISTSERV{([at]})nowhere.xy
