Ikena Forensic FAQ

What is Ikena Forensic?

Ikena Forensic is a video enhancement software application featuring MotionDSP’s patent-pending super-resolution technology. Able to run on any Windows PC (laptop or desktop), its powerful multi-frame enhancement technology can quickly and significantly improve poor video from less-than-ideal sources, such as consumer mobile phones, digital cameras, or surveillance cameras.

What file formats can Ikena Forensic import and export?

Ikena supports several input file formats, video codecs, and audio codecs, including the following:

  • DVR Format: With added SiraView support Ikena Forensic now supports many of the follwing DVR Formats.
  • File formats: DV, Flash, Real, WindowMedia, Quicktime, AVI, 3GP, 3G2, MP4
  • Video Codecs: Uncompressed RGB, H264, MPEG-4, H263, WMV7, WMV8, WMV9, VC-1
  • Audio Codecs: MPEG, AC3, AAC, WMA, ADPCM, AMR

Ikena Forensic can export both high-res still images, and high-res video.

High-res stills can be exported in uncompressed BMP, compressed JPEG, PNG and TIFF formats. High-res video can be exported in uncompressed AVI, Motion-JPEG-compressed AVI, XVID-compressed AVI, Digital Video DV25 and Windows Media Video WMV.

How is Ikena Forensic different from other video forensic applications?

First-generation video forensic software packages were designed to be used by highly-skilled video forensic technicians. Ikena was designed to be automated, fast, and usable with very little training.

Ikena's patented super-resolution algorithms differ from Frame Averaging (also known as Integration) in several ways:

  1. Frame averaging doesn't increase resolution (i.e., the resolution of your output is no higher resolution than your input resolution).
  2. Frame averaging can't deal with any motion (as it just averages the pixels at the same spatial positions in all frames). If there is any movement between frames, frame averaging falls apart.
  3. Frame averaging requires manual "de-warping" of video frames. If there has been any geometric distortion between the frames (for example, if the camera or object angle changes slightly), each frame needs to be "de-warped" manually. Manual de-warping is possible using fairly simple methods (translation, rotation, or zoom) and it may work only for rigid objects/areas. MotionDSP's super-resolution provides for sophisticated, and automatic de-warping of frames, without any manual steps. 
  4. In addition to points 1-3, super-resolution is superior to frame averaging because it uses much more sophisticated "pixel combination model". -- that is, super-resolution selects the best pixels for re-construction.

For example, in Frame Averaging, when you frame average 10 frames, the math is:

  • Output = (Input1 + Input2 + ... + Input10)/10
  • Super-resolution, uses a statistically and content-optimized function of the 10 input values
  • Output = complex_function {Input1, Input2, ...., Input10}

What is the difference between Ikena Forensic and Ikena Forensic Pro?

Ikena Forensic and Ikena Forensic Pro are identical in their basic feature sets.

What sets Ikena Forensic Pro apart from Ikena Forensic is speed. Ikena Forensic can use CUDA-compatible graphics cards from NVIDIA, and with a high-end card like the NVIDIA GeForce GTX 780 or Quadro K5000, it can process video 10 times faster than a high-end Intel CPU. We've used a 6-core Intel CPU below. For 2 and 4-core CPUs, the difference is even greater -- up to 15x faster.

In addition, Ikena Forensic Pro comes with Ikena Spotlight and Ikena Measure included in the purchase price.

Can Ikena Forensic Process HD Video?

Yes, Ikena Forensic, Ikena Forensic Pro, and Ikena ISR can all process HD video, up to 1080P (1920x1080).

Performance (speed of processing) will depend on the PC hardware used, and the settings used in Ikena.

We recommend the highest powered GPUs for HD processing (such as the NVIDIA K5000 GPU).

Due to video file resolution limitations, some filters, such as MotionDSP's super-resolution algorithm (called "resolution" in Ikena Forensic) will be limited to certain SR zoom factors, but this can be mitigated with the use of the "region of interest" control, which limits processing to a certain area of the screen.
