> What is dVeloper?

Many times crucial details are hidden in video due to poor lighting or improperly adjusted and maintained cameras and video equipment. When dealing with color video, details are often more prevalent in one color than another. With dVeloper, it's easy to isolate the video color space that holds the most valuable information. With the click of the mouse, dVeloper compensates for the poorly exposed video. By analyzing the entire video, or just a region of interest, dVeloper automatically adjusts brightness, contrast and gamma to bring out more detail.

dVeloper removes noise and video graininess through a time-lapse processing technique called frame averaging. When the target remains still for even a moment, video noise and other transient items like rain and snow are removed, revealing the details hidden beneath. 


> dPlex & dPlex Pro - What is multiplexed video?

Security cameras often store video in a multiplexed video format. Instead of an individual video recorder for each camera, the security system rotates through the cameras and records an individual image from each camera to a single video recorder.  The reordering process goes something like this (keep in mind there are 30 frames per second available on NTSC video):

Camera 1/Frame 1 - Camera 2/Frame 2 - Camera 3/Frame 3

Once the rotation is complete, the recording goes back to Camera 1 and starts the whole process over again. dPlex, from Ocean Systems, is a universal video demultiplexing tool that allows you to isolate individual cameras from multiplexed video.  The results are amazing.


> What is Magnifi?

Magnifi enlarges a section of the video and displays the result either full screen, or to a user defined portion of the screen. Once the target area is defined, and an output mode is selected, the analyst magnifies the image using the zoom control. The analyst can leave the enlarged image as is, or select a mathematical filter to further clarify the results. Magnifi provides independent controls of both target and output borders. These are especially useful when presenting the results in court.

You have complete control over the Target and Output Border color, shape and size. For your output, you can choose from four output views (off, full, 90% full, and quad), adjust a variable zoom control, adjust brightness, contrast, gamma and opacity, rotate your footage 360 degrees, and apply any of 12 mathematical filters to further clarify the results.


> What is Spotlight? 

Spotlight is a quick and easy to use dTective module that allows the analyst to select a region of video highlight or blur.  You can define a shape anywhere from a square to a circle, then work with either the inside or outside of that shape using different filters, including blur, mosaic and scatter. All of these filters have a variable intensity setting.  You can even apply a border color to the shape to focus more attention on your area of interest.  All of the settings can be changed over time, allowing you to track a face or object as it moves as well as adjust your settings to accommodate for the object changing size as it gets closer or further away in the video.


> What is arithMATIC?

arithMATIC allows you to perform mathematical operations on a single video clip or you can two do comparisions between 2 pieces of video.

Listed below is a summary of the tools available in the arithMATIC plug in:

Addition - will allow the user to brighten an image by adding the corresponding pixel values from two tracks of video.

Subtraction - will allow the user to see what has changed between two images by subtracting the pixel values of the second video track minus the corresponding pixel values from the first video track.

Multiplication - will also allow the user to brighten the image by multiplying the corresponding pixel values from two tracks of video.

Division - will also allow the user to perform change detection in the image by dividing the pixel values of the second video track by the corresponding pixel values from the first video track.

Scaling - is a subset of the Multiplication function. It allows the user to multiply the two tracks by a number of greater than 1 to brighten the image and less then 1 to darken an image.  Scaling works on all four modes.


*********************************
BONUS INCLUDED: DVR dCoder v2.5.1

Digital surveillance video presents unique and often frustrating challenges to a forensic video analyst. Many times the digital file is recorded in a proprietary format and it requires a proprietary player to simply view the file. DVR dCoder solves this problem.

DVR dCoder is designed to solve the problem of working with proprietary digital surveillance files so potentially case breaking evidence is easy to access.

Simply play the digital surveillance file and allow DVR dCoder to capture the video.  This captured footage is a duplicate of the original file in an uncompressed digital format. Once captured, import the media into your dTective system for further examination.
