Task 2: Create a Snapshot

In this task we will create a snapshot, which is a single frame extracted from the video and written to disk as an image file. Snapshots can be written as raw (georeferenced) or resampled (geocoded), or both.


2. Hit the Create Snapshot button in the video window to extract a snapshot from the video. Raw and/or resampled snapshots are extracted and written to disk based on the check boxes on the Clipmarks tab.

3. In Windows Explorer, browse to the C:\Temp\Snapshots folder.

Snapshot files are automatically named as videoName_date_time_type.tif, where date_time = mission date (YYYYMMDD) and UTC time (HHMMSS) and type = raw or res (for resampled). The raw snapshot file is placed on the Windows clipboard and can be pasted into applications such as PowerPoint. If only resampled snapshot was specified then the resampled snapshot is placed on the Windows clipboard. Snapshots can also be created using the hot key defined for snapshots in the configuration file (default Alt-S).

4. Double-click on one of the snapshot files to display the snapshot in the registered viewer for TIFF files.

Task 3: Looking at the Video Window Tabs

In this task we will look at the features and functions of the tabs on the video window.

1. Hit the Loop button to loop play the video.

2. Click on the Data tab.

55

a) Note the real-time readouts of the video telemetry. Which fields are shown

and the order they are shown in the list can be customized in the

MVA configuration file.

b) Check and uncheck Show MGRS.

c) Check and uncheck Use ground points if available. This video contains

both ground corner points of the frames, and location and angle

information of the sensor.

d) Pull-down the Camera designation field to see the available choices that

are delivered with MVA. Users can specify additional camera

designation files in the MVA configuration file, and they will appear

in this list.

3. Click on the Display tab.

a) In the video window, uncheck Display video in map window. The

tracking graphics are still displayed, but the video frames are no

longer displayed. Check Display video in map window to see the

video frames again.

b) In the video window, uncheck Display tracking graphics in maps. The

video frames are still displayed, but the tracking graphics are no

longer displayed. Check Display tracking graphics in maps to

see the tracking graphics again.

c) Click on the Translucency up-arrow repeatedly to move from 0% to 100%,

and from 100% back to 0% to change amount of blending of video

frame with background image and graphics in the map window.

d) Check Ghosting to leave previously displayed video frames in the map

window. The previous video frames are erased when the map

window is shifted or zoomed. Uncheck Ghosting.

4. Click on the Enhancements tab.

a) Check Digital zoom and adjust the Scale slider. Sliders are available to

adjust the portion of frame which can be seen in the video window.

Uncheck Digital zoom.

b) Check Brighten and adjust the Gamma and Brightness sliders left and

right to desired values. The video is dynamically enhanced in the

video window and in the map window as the sliders are moved.

Check Auto brighten to automatically adjust the brightness of the

video dynamically as the video plays. Uncheck Brighten.


c) Check Dehaze and uncheck Auto dehaze. Adjust the Foreground,

Background, and Lightness sliders left and right to desired values.

The video is dynamically enhanced in the video window and in the

map window as the sliders are moved. Check Auto dehaze to use

default values. Uncheck Dehaze.

The Dehaze filter enhances a video by removing the scattered light and restoring the light absorbed by the atmosphere. The process is adaptive for each pixel in the frame, and tries to produce the best frame possible based on a number of metrics. The filter may be used in a fully automatic mode, or it can be adjusted by adjusting the three sliders on the filter. The three sliders simply multiply the adaptive results. The ranges of 0 to 5.0 represent a multiplier for each adjustment. The default values are 1.0. These sliders increase or decrease the values calculated by the adaptive algorithm. The Foreground slider adjusts the amount of light scattered by the atmosphere and the primary cause of haze. It primarily impacts the foreground of the frame, and hence its name. The Background slider adjusts the amount of light transmitted through the atmosphere. Since the distance the light travels through the atmosphere is greater in the background, its effects are more noticeable in the farthest distances of the frame. The Lightness slider adjust the amount of light for each pixel in a nonlinear fashion similar to a gamma correction. All three sliders interact and are not independent of the other. The fully automatic mode uses the default values for foreground, background, and lightness.

d) Check Intensity range. Move the Upper range slider all the way to the

right. Move the Lower range slider to approximately 200. This is

used to highlight brighter values in the video, which is useful for

identifying hot spots such as people and vehicles in video from

infrared (IR) sensors. Uncheck Intensity range.

e) Check Intensity centroid stabilize and adjust the Stabilize intensity

level slider. The frame is shifted in the video window to keep

moving objects centered. Uncheck Intensity centroid stabilize.

f) Check Average and adjust the Number of frames slider. The frames are

averaged to provide a smoothing effect. This is often used with

Intensity centroid stabilize. Uncheck Average.

5. Select the Clipmarks tab. The list of predefined clipmark names, descriptions, and

hot keys can be customized in the MVA configuration file. You can also place

57

custom clipmarks. You can specify whether to create resampled (geocoded)

snapshots, raw (georeferenced) snapshots, both, or neither.


Task 4: Register Video to Reference Image
