MotionTracking MK-II Plus

AviUtl object tracking (rubbish) plugin based on LKT/optical flow. Use OpenCV 4.9.0 or newer.

System Requirement

*- CPU with AVX support (Not tested on SSE-only CPU)
*- >= 2GB RAM
*- Windows 7 or later
*- AviUtl 1.10
*- Adv.Editing 0.92

Installation

Dump the .AUF and MotionTracking_model folder into
your favorite folder where AviUtl loads filter plug-ins

The menu name should be "MotionTracking MK-II Plus"

Additional work is required if Methods 4, 5 or 6 are to be used.

For Method 4 (DaSiamRPN)

  1. Download the following file from the URL listed as a comment out in the source code at this URL
  • dasiamrpn_model.onnx
  • dasiamrpn_kernel_r1.onnx
  • dasiamrpn_kernel_cls1.onnx
  1. Dump each files into MotionTracking_model folder

For Method 5 (Nano)

  1. Download the following file from this URL
  • nanotrack_backbone_sim.onnx
  • nanotrack_head_sim.onnx
  1. Dump each files into MotionTracking_model folder

For Method 6 (Vit)

  1. Download the following file from this URL
  • vitTracker.onnx
  1. Dump each files into MotionTracking_model folder

Helper Plugins

The single AUF actually contains two more helper plugins:

  1. Pre-track: HSV Cvt
  2. Pre-track: BGSubtraction

HSVCvt convert the RGB image into HSV, then display it as if RGB. It can also display only one of the HSV channels.

BGSubtraction aims to isolate the moving object from the background. It can output the isolated RGB image, or output a grey-scale mask. Beware that a large Range value may cause out-of-memory problem, or enable Large-Address-Aware to get around.

Save EXO

Auto correct for single sandwiched error result.
Support CJK filename

Options

Method

Specifies the algorithm to be used in the analysis.

  4. DaSiamRPN
  5. Nano
  6. Vit
Rect Hue

Specifies the hue of the rectangle displayed in Object Selection and View Result.

Save EXO Options

  • Easy Privacy : Blur all detected faces(real face only), No tracking is needed. Works well on frontal face, poor on profile face.

Pre-track:BGSubtraction

Common Parameters

  • Range : Use no. of frames before and after current frame for analysis.[30]
  • Shadow : 1= Extract shadow [0]

MOG2-Only

  • NMix : Number of Gaussian mixtures [5]
  • BG% : Background ratio [70%]

KNN-Only

  • d2T : Threshold on the squared distance between the pixel and the sample to decide whether a pixel is close to that sample.
