FAQ

What is Ikena?

Ikena 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 import and export?

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

  • 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 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 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 and Ikena GPU

Ikena and Ikena GPU are identical in their basic feature sets.

What sets Ikena GPU apart from Ikena is speed. Ikena GPU can utilize OpenCL or CUDA-compatible graphics cards from AMD and NVIDIA, and with a high-end card like the AMD FirePro(TM) V8800, Ikena GPU can process video up to 6 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 GPU comes with our Evidence Spotlight tool included in the purchase price, a $1000 value.

Can Ikena Process HD Video?

Yes, Ikena, Ikena GPU, 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 Tesla C2050 GPU).

Due to OS memory limitations, some filters, such as MotionDSP's super-resolution algorithm (called "resolution" in Ikena) 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.

What is the difference between Ikena and vReveal?

vReveal is a consumer product from MotionDSP which is designed to make consumer videos "look great" -- improving the subjective quality of the video, but it is not designed, licensed, or recommended for any forensic use.

vReveal does not use MotionDSP's patented, automated super-resolution technology, and thus, vReveal won't help you reconstruct and read license plates from security videos, or grab high-res images of faces from video. For that, you need Ikena.

Ikena has been designed from the ground up for video enhancement for law enforcement and forensics labs, with powerful tools for capturing, enhancing and presenting court-admissible evidence. It uses MotionDSP's patented, automated super-resolution algorithms to reconstruct each frame of video with the best information from surrounding frames of video, objectively increasing resolution and detail while significantly reducing noise. It was developed with direct input and requirements from several of the world's leading video forensic labs. Results from Ikena have been used to prosecute court cases in both the US and the UK.
