Программы для настольного компьютера

ак
видите, КПК на платформе Palm может стать очень полезным помощником для любителей
астрономических наблюдений  тем более что небольшие размеры позволяют легко
носить его с собой и использовать в полевых условиях. Впрочем, если КПК нет,
то можно воспользоваться и настольным компьютером, а при наличии ноутбука или
планшетного ПК  взять с собой и его.

StarCalc

У отечественных астрономов-любителей StarCalc является одной из наиболее известных
и популярных программ. В StarCalc нет ничего лишнего: она работает очень быстро
и не требует больших системных ресурсов (рис. 8). Кроме того, программа создана
российскими разработчиками, и поэтому интерфейс и экранные сообщения выполнены
на русском языке.

рис. 8

В StarCalc имеется весьма интересная функция, изменяющая цвет неба. Как только
программа определяет, что наступил рассвет, фон небесной карты начинает постепенно
светлеть. Наряду с этим с карты исчезают и небесные объекты, которые при такой
яркости неба уже не видны. С наступлением вечерних сумерек начинается обратный
процесс.

SkyCharts

Флагманской в кругу астрономов-любителей считается программа SkyCharts  Атлас
неба (рис. 9). Изначально она была разработана во Франции, однако в настоящее
время доступно множество локализованных версий, в том числе и на русском языке.

рис. 9

Создателям SkyCharts нельзя отказать в хорошем вкусе: программа очень красиво
оформлена, поэтому хочется лишний раз ее запустить, чтобы просто полюбоваться
красиво светящимися звездочками. Правда, подобная красота требует определенных
жертв: SkyCharts работает значительно медленнее отечественной StarCalc, требует
гораздо больших системных ресурсов и с позиции начинающего астронома имеет большое
количество редко используемых функций.

Virtual Moon

Луна  первый небесный объект, который с раннего детства привлекает внимание
человека. Достаточно взять в руки небольшой бинокль, и взору наблюдателя откроются
многочисленные равнины и кратеры естественного спутника Земли

На многие вопросы
пытливых наблюдателей даст ответы незатейливая программа Virtual Moon: когда,
где и какие космические аппараты были запущены к Луне, как называются кратеры
и горы и пр. Также можно дополнительно скачать с сайта разработчика потрясающие
снимки лунной поверхности.

На прилагающемся к журналу компакт-диске вы сможете найти некоторые из описанных
в статье программ, а также ссылки на соответствующие веб-ресурсы.

Installing the plug-in

To install the Neat Video OFX plug-in:

1. Make sure you have started Nuke at least once before installing the plug-in. If you
   have not done that yet, start Nuke and exit it.
    
2. Download the installer of Neat Video for OFX hosts:

• If you already purchased the product and have a current license for the Pro plug-in,
  please download the Pro plug-in from My Products
  page
• If you want to try Neat Video before purchase, please download the Demo plug-in from
  Download page

1. Starting the installer:

For Windows:

Double-click the downloaded EXE file to start the installer

For Mac OS X

a. Double-click the downloaded DMG file to mount the volume
b. In the mounted volume, double-click NeatVideoOFX.Intel.pkg to
start the installer
    (you may be prompted to enter the Name / Password of the OSX
administrator account)

For Linux:

Double-click the downloaded package NeatVideoOFX.Intel64.tgz to
open the archive and extract the installer from it (
NeatVideoOFX.Intel64.run)
(you may be prompted to enter the Name / Password of the administrator account)

1. Proceed through the steps of the installation process. Use the default settings offered
   by the installer.
    
2. Start Nuke and right-click in the Node Graph panel in the main
   window of Nuke. Then find Neat Video > Reduce Noise v4 in
   the list.

In case the plug-in has not become available in Nuke, please contact
Neat Video support for assistance.

Running Neat Video on a sample video clip

Please download the test-kit prepared to
help you start using Neat Video. Having downloaded, please unzip it to a new folder on the
hard disk.

The test-kit includes a sample video clip: SampleClip.mp4. This
is a typical video clip captured by a digital video camera in high-gain mode. Some
technical information about the sample clip is available in the
SampleClipInfo.txt file.

Please start Nuke and go through the steps below to clean the clip using Neat Video.

2.1. Add the sample clip to the project

2. Importing a media file

1. Right-click in Node Graph tab to open the popup menu and
   select Image > Read.
2. Navigate to the folder with input clip, select SampleClip.mp4
   .
3. Make sure the frame rate is set to 25fps.

A node with the sample clip will appear in the Node Graph panel in
the bottom of the main window of Nuke:

1. Connect the Read1 SampleClip.mp4 node to the
   Viewer1 node to see the preview.
   The Nuke preview window will display the sample clip and you will see that there is
   strong noise in it. The task of Neat Video is to reduce this noise.

1. Right-click Read1 node.
2. Find Neat Video > Reduce Noise v4 in the list:

2.3. Configure Neat Video

1. Open Neat Video plug-in window

1. Select Reduce Noise v4. This will add a node with Reduce Noise
   v4 into the Node Graph and enable controls in the
   Properties panel in the right part of the main window of
   Nuke.
2. Select a frame for noise analysis using the selector in the timeline range.
3. Click Prepare Noise Profile in the
   Properties panel to open the Neat Video plug-in window.
   (If you run the Demo plug-in, click OK in the popup splash
   screen of the plug-in to proceed further).

The Neat Video plug-in window will open and display the current frame from the clip.

1. At this point Neat Video will ask to specify the scan type of the clip. Please select
   Progressive.
2. Click the

   button in the bottom of the Neat Video window and select
   Linear :

2. Build a noise profile for the clip

To reduce noise in this frame and in the whole clip, Neat Video generally needs a noise
profile describing the noise properties of the clip. You can prepare such a profile using
the Auto Profile function:

1. In the Device Noise Profile tab   

      click   

Neat Video will then automatically analyze the noise to build a new noise profile:

1. Visually inspect the selected area — it should contain no visible details,
   only noise; otherwise the noise profile and subsequent noise reduction may be
   inaccurate.

If the selected area does contain any details, move the selection to a featureless area or
simply draw a new selection in such an area (the selection must be at least 32×32 pixels
large). Then click the Auto Profile button again.

1. After that Neat Video is ready to filter the clip.

3. Check Preview

Switch to the Noise Filter Settings tab 

You will notice that Neat Video has already applied noise reduction based on the default
filter settings and the preview shows a clearly visible difference: there is less noise
than in the original frame.

You can try to adjust the filter settings and see how that affects the results. For
example, try to adjust the Temporal Filter > Radius
setting (in the Temporal tab in the Filter
Settings box in the right part of the window) from 2 to 1 or to a higher value. This
will apply weaker or stronger temporal noise reduction to the frame.

4. Apply the changes
 

Click 

  in the bottom of the plug-in window.

Neat Video will save the current settings and close its main window.
(If you run the Demo plug-in, it will also describe the limitations of the Demo version at
this point).

Once this step is completed and Neat Video window is closed, the filter is ready for
work.

The Nuke preview window now shows the clip with noise reduction applied to it:

2.4. Further steps inside Nuke

To apply Neat Video noise reduction

1. Create a write node (menu Image > Write), link it (after)
   to the Reduce Noise v4 node, set up the parameters of the
   write node and then start render using the Render button.
2. Go to menu Render > Flipbook
   Selected.

This will automatically apply Neat Video noise reduction to the sample clip and save the
result to a new video file on the hard drive. You will then be able to open this new file,
evaluate the filtration results and adjust the filter settings if necessary.

Please see the User Guide (Win),
User Guide (OS X) and
User Guide (Linux) for more details about
adjusting the filter settings and other aspects of using Neat Video. These
Video Tutorials will also help you to get the most
out of Neat Video noise reduction.
