What's new in Centertracker Deluxe 2.1.2
Oct 8, 2012
- improved/ added:
- old result files (video.avs, x.txt etc.) get deleted when in same directory of current video (this relieves the user from doing that manually)
- increased memory for templates (if template is too big and parameter pixels/ dot is too small processing may halt though. To prevent that you have to upgrade to CT deluxe which has increased processing speed)
- fixed:
- bug in template mode 2 (detect object size): if template is rather thin than wide this bug results in less tracking precision
- color space issue with border filling method ''mirrored'' (color artefacts are now a thing of the past)
New in Centertracker Deluxe 2.1.1 (Jul 31, 2012)
- improved/ added:
- optimized code (faster processing, random test yielded 11% speed increase)
- fixed:
- wrong order of displayed RGB values for Overlay corrected
- removed some minor bugs
New in Centertracker Deluxe 2.1 (Mar 14, 2012)
- improved/ added:
- automatic zoom speed detection for template mode 2
- fixed:
- visualization of opacity and transparent color of the overlay image was not correct for opacity values < 100; now it should correspond 1:1 to AviSynth
New in Centertracker Deluxe 2 (Mar 12, 2012)
- added:
- overlay image option for template modes
- zoom speed for detecting object size in template mode
- improved:
- object size recognition for template mode 2 is more accurate now (and more similar to mode 1)
New in Centertracker Deluxe 1.9.1 (Mar 12, 2012)
- added:
- in brightness mode there are two options available now: relative and absolute (new option) brightness. Relative means that the brightness is chosen relative to the darkest (resp. brightest) pixel in the frame so that values in the selected range above (below) that pixel are shown in white. Absolute is trivial: values below (above) the selected value are shown in white.
- Absolute is usually faster than relative except for blank frames, so you can speed up processing a bit by choosing absolute (default)
- fixed:
- minor bug with bright objects in brightness mode (relative brightness had wrong (darkest) reference pixel)
New in Centertracker Deluxe 1.9 (Mar 12, 2012)
- added:
- additional template mode (mode 2): uses method similar to function cvMatchTemplate but is not based on it (as mode 1). Mode 2 is fully configurable so you can determine processing speed (either faster or slower than mode 1) and it includes an option 'detect object rotation' which can only be ticked if 'detect object size' is ticked, too. For more info please refer to the file 'tmg_guide.pdf' either by opening it from the program directory or by clicking the 2nd icon at the top of the starting window (next to the 'how to' icon)
- improved:
- direct execution of the file 'video.avs' is now possible (default: 'open avs file when done'); please link avs files to VirtualDub
New in Centertracker Deluxe 1.8.3 (Mar 12, 2012)
- improved:
- template mode: in follow mode you can now choose any frame for your template without any problems (so far the program would usually not find the template if it had been chosen in a frame different from frame 0). No matter where the object will reappear Centertracker will find it again if it has not changed too much and if the similarity parameter has been chosen carefully.
- The time needed for calculation in 'empty' frames will be more (as it scans the whole frame while in previous versions it only scanned the detection area). So you may rather work with v. 1.8.2 if your object reappears in the same area as it disappeared and if you choose it in frame 0 because that version is faster and as accurate as version 1.8.3 in that case - but only in that case
New in Centertracker Deluxe 1.8.2 (Mar 12, 2012)
- fixed: template/ detection area selection issue (if you do not choose the upper left corner with the first left click and the lower right corner with the second left click an error will occur)
- improved:
- slider control handling
- you do not have to change the avs file manually anymore if you use other file formats than avi (uncheck box 'source video is avi')
New in Centertracker Deluxe 1.8.1 (Mar 12, 2012)
- fixed:
- memory bug (occurs when you wait during settings adjustment)
New in Centertracker Deluxe 1.8 (Mar 12, 2012)
- fixed:
- trackbar bug in brightness mode (wing beat compensation, limit detection area ticked)
- improved:
- brightness mode faster now
- trackbars replaced by new sliders with fine tuning buttons (so far the trackbar windows would fill a lot of space on the screen, now this space has been reduced a lot)
New in Centertracker Deluxe 1.7 (Mar 12, 2012)
- added:
- an additional method for wing beat compensation. The method is explained in the file wbc_guide.pdf which you can find in the program directory or by clicking on the bird in the starting window. If you do not want to use it set the mass trackbar to 120. The values and axes will still be shown but the method will not be applied. I have developped this method to increase the range of wing beat detection in cases where the flight phase is a bit more ''complicated'', e.g. when the bird is seen from the side. Neither method is absolutely accurate but the user can specify some parameters to improve results.
New in Centertracker Deluxe 1.6.4 (Mar 12, 2012)
- fixed:
- minor bugs in object size detection (detection area adapts more accurately now, exceptions that could cause a preliminary program termination have been fixed)
- improved:
- you don't have to wait anymore until all frames are loaded in template mode, you can now skip at any time
New in Centertracker Deluxe 1.6.3 (Mar 12, 2012)
- added:
- for template follow mode:
- detect object size: this will increase detection reliability in many cases but it can be very slow
- similarity trackbar: if the object moves out of the frame and back into it again, i.e. if it becomes invisible for a moment, so far Centertracker lost track of the object. By increasing the similarity value you set a minimum for the similarity between template and object in the frame. I.O.W.: if similarity is set to zero (default) the detected area can be any region of the frame - just like in previous versions. By setting it to 1000 (maximum) template and detected area have to be an exact match. Thus, with changing objects the maximum value will result in no detection. Tested values between 900 and 950 for a ''re-appearing'' object have yielded acceptable results (if the object does not change too much while it's ''gone''.
