*Classes*

1. ConfigReader

   ○ Attributes:

     ■ config_path (str): The path to the configuration file.

     ■ config_parser (ConfigParser): An instance of a configuration parser.

   ○ Methods:

     ■ __init__(self, config_path=None, configName=None): Constructor to initialize with an optional config path.

     ■ getImageName(): Returns the image name.

     ■ getProjectedOverlayAlphaWidth(): Returns the width of the projected overlay alpha.

     ■ getProjectedImageWidth(): Returns the projected image width.

     ■ getTransparencyFactor(): Returns the transparency factor as a float.

     ■ saveConfig(path): Saves the configuration to the specified path.

     ■ getImageSide(): Gets the side of the image.

     ■ setParameters(parameters): Sets parameters for the configuration.

     ■ getGamma(): Returns the gamma value.

2. ProcessImage

   ○ Methods:

     ■ processImage(image_path, params, main_display): Processes the image located at image_path with specified params, using MainDisplay instance for display 

       purposes.

3. MainDisplay

   ○ Methods:

     ■ readImage(image_path): Reads an image from the specified path and returns it as an ndarray.

     ■ setImage(image): Sets the image to display as an ndarray.

4. MaskCreator

   ○ Attributes:

     ■ _image (ndarray): Stores the original image.

     ■ _alpha_gradient (ndarray): Stores the alpha gradient.

     ■ _gamma_corrected (ndarray): Holds the gamma-corrected version of the image.

     ■ _mask (int): Represents the mask value.

     ■ transparency_factor (float): Factor controlling the transparency.

     ■ result_image (ndarray): Holds the result after processing.

   ○ Methods:

     ■ __init__(_image, transparency_factor): Initializes with an image and transparency factor.

     ■ createMask(image_side, mask_width, image_width): Creates a mask for the specified image side and dimensions.

     ■ smoothStep(edge0, edge1, x): Returns a smooth transition between two edges.

     ■ gammaCorrection(gamma): Applies gamma correction.

     ■ alphaBlending(image_side): Performs alpha blending for the specified side.

5. ImageProcessingApp

   ○ Attributes:

     ■ left_image_path and right_image_path (str): Paths to the left and right images.

     ■ left_params and right_params (dict): Parameters for left and right images.

     ■ processed_images (dict): Dictionary to store processed images.

     ■ notebook (Notebook), tab_left, tab_right, tab_settings, tab_preview (Frame): UI components.

     ■ process_button (Button), progress_bar (Progressbar): UI elements for processing and progress indication.

     ■ left_image_label, right_image_label, original_image_label, processed_image_label (Label): Labels for displaying images.

   ○ Methods:

     ■ __init__(root): Constructor to initialize the application with a root UI element.

     ■ setupLeftTab(), setupRightTab(), setupSettingsTab(), setupPreviewTab(): Methods for setting up respective tabs in the UI.

     ■ selectLeftImage(): Allows selection of the left image.

     ■ saveConfiguration(), loadConfiguration(): Methods to save and load configuration.

     ■ processAndSave(): Processes and saves the image.

     ■ displayPreview(): Displays a preview of the processed images.

     ■ displayImage(processedImages): Displays an image from processed images.

Relationships

   ● ImageProcessingApp is the main application class and interacts with ConfigReader, ProcessImage, and MainDisplay classes.

   ● ConfigReader provides configuration details to ImageProcessingApp.

   ● ProcessImage uses MainDisplay to load and display images, possibly utilizing MaskCreator for mask and blending operations.

   ● MaskCreator handles the creation of masks and alpha blending, which may be used by ProcessImage to prepare images for display in MainDisplay.
