Overview Apps

When you open a project in PyCharm, the user interface will show the default main window ready to run looks as follows:

Here is detail explanation

1. Open media source

The inputs offered by MoilApp include picture files, video files, and cameras—USB cameras, web cameras, and streaming cameras from Raspberry Pis—all of which can be used for processing. Simply tap the appropriate button for the media source you want to process, and the software will open a file explorer popup similar to the one below.

- After selecting the file to open, a combo box prompt will appear asking you to select the type of camera that was used. The camera parameters can be loaded from the database using this.

- There are two ways to open the camera: through USB or via streaming. You can use the combo box to pick the USB port that is being used for a camera, click "OK," and you will be prompted to select the type of camera that is being used. As depicted in the picture below.

- The streaming cam option allows you to access the raspberry-pi camera using the stream server URL. You merely need to enter the camera's URL and push the "oke" button, as seen in the example below. In the combo box prompt, you will be prompted to select the type of camera being utilized.

2. Rotate Image

MoilApp has two rotate functions: rotate the left image and rotate the right image. Each rotate image can be operated by entering a value on the rotate scale; this is so that users can rotate with less scale.

3. Zoom Image

The user can zoom in and out using the plus and minus buttons, respectively, in this program. In addition, the user can select the zoom scale to be smaller by a minimum of 25 degrees and above. to make the final image clearer.

4. Default Application

The application will automatically return to the original image when the default button is clicked when the user is processing an image, for instance when the user is processing an image to any point and then decides they want to go back to the original image, where this position is the position when the user loads the image when opening the application.

5. Add Plugin Applications

When the user wants to create an application integrated with MoilApp or the user wants to open the application, the user can add the application to MoilApps by clicking the Add button at the top of the application, provided that the user creates the application using MoilDev or MoilUtils-Templates.

6. Information Applications

The users can view related information on MoilApp by accessing further information.

7. Recording Screen

A new feature offered by MoilApp is screen recording, which makes it simpler for users to do so. This tool is also a helpful way to record and share videos of what is happening on your desktop.

When using a desktop application to record your screen, you'll typically have a few options to choose from. First, you'll need to select the area of your screen that you want to record. Some applications allow you to record your desktop, while others let you region of your screen.

8. About US

The application's "About Us" section contains details about our work in the field of fisheye image processing.

9. Theme Application

In order to assist users adjust to their eyes and avoid seeming monotonous while using this software, MoilApp offers two themes for use: one in bright mode and the other in dark mode.

10. Hide Button Application

By using the "ESC" key on the keyboard, users can also conceal or reveal the title of the button or view the button's functionality in the application.

11. Fisheye View

The user interface will display the Anypoint image or Panorama image as shown below when the user chooses to process the original fisheye image by using the Anypoint or Panorama button on the user interface.

We offer controls for video and camera media, including play, pause, stop, forward, backward, and a slider timer. Where image processing can be facilitated by the use of this controller.

12. Anypoint View

Sometimes we only want to look at places where there is a lot of information in order to improve the outcomes of observations. As a result, we can apply the approach of the undistortion rectilinear selected image. This approach shifts the optical axis to the specified zenithal (alpha) and azimuthal (beta) angles, then converts the image plane coordinate to hemispherical coordinates. Anypoint view has two modes, with mode 1 being the result of alphaOffset degree rotation followed by betaOffset degree rotation around the Z-axis (roll) (pitch). In contrast, mode-2 produces a thetaY degree rotation around the Y axis (yaw) following a thetaX degree rotation around the X axis (pitch).

You can switch from mode 1 to mode 2 or vice versa by pressing the help button when in Anypoint view mode. The help button can also be used to view Anypoint results coming from a certain angle. An overview of the additional button in Anypoint view mode may be found below.

13. Panorama view

As explained earlier, the panorama view may present a horizontal view in a specific immersed environment to meet common human visual perception. The figure below shows a diagram of transforming a fisheye image into a panoramic view.

The image below is the result of image processing panorama view.

- The maximum and lowest FoV values can also be changed using the lineedit feature, which is only available in this mode.

- By clicking the save image button or selecting save image from the context menu when you right-click on the result image, you can save the original image or the result image. When you save an image for the first time, the application will open a dialog box asking you to select the directory you want to utilize as storage.

- Use the record button to start recording a video; it works almost just like storing an image.You will be asked to select a directory before you can begin recording, and the video files will be saved there.

14. Camera parameters

The camera parameter is a very important component in fisheye image processing. Each fisheye camera can be calibrated. and derives a set of parameters by the MOIL laboratory before the successive functions can work correctly, configuration is necessary at the beginning of the program. MoilApp provides a form dialog that can add, modify, and delete parameters that will be stored in the database. To be able to use this feature, please click on File >>.Camera Parameters. The overview of this form is shown in the picture below:

- If you want to see the parameter, you can list the camera type from comboBox list parameter If you are using a camera whose parameters are not yet available in the database, you can add them. You just need to write all the parameters on the form, then click the "new" button. after that the data will be saved and you can use the camera parameters.

- Modify camera parameters If you want to change the value of the parameter, you can modify it. select the camera type in the list parameter combobox, then you enter the new parameter value. click the update button and the modified parameters will be saved in the database.

- You can also delete parameters by pressing the delete button on the selected parameter list.

15. Clear User Interface (UI)

Clear UI is the latest feature from MoilApp. This feature is used to clean images on the user interface, Usually, if you don't use Clear UI, when the user opens the application again, the user is faced with the previous task when processing images; therefore, this feature is used to clear data on the user interface.

16. Check for Updating

Checking for updates is an additional feature of the MoilApp update; this feature is used if the user wants to update the application from the developer server. The use of this feature greatly facilitates the user without having to open a terminal to do the installation or update manually.
