Functions/GenXdev.AI.Queries/Update-AllImageMetaData.ps1

###############################################################################
<#
.SYNOPSIS
Batch updates image keywords, faces, objects, and scenes across multiple system
directories.
 
.DESCRIPTION
This function systematically processes images across various system directories
to update their keywords, face recognition data, object detection data, and
scene classification data using AI services. It covers media storage, system
files, downloads, OneDrive, and personal pictures folders.
 
The function processes images by going through each directory and processing files
individually. DeepStack functions (faces, objects, scenes) are performed first,
followed by keyword and description generation. This ensures optimal processing
order and outputs structured objects compatible with Export-ImageDatabase.
 
This allows for structured data output for pipeline operations like:
Update-AllImageMetaData | Export-ImageDatabase
 
.PARAMETER ImageDirectories
Array of directory paths to process for image keyword and face recognition
updates. If not specified, uses default system directories.
 
.PARAMETER ContainerName
The name for the Docker container used for face recognition processing.
 
.PARAMETER VolumeName
The name for the Docker volume for persistent storage of face recognition data.
 
.PARAMETER ServicePort
The port number for the DeepStack face recognition service.
 
.PARAMETER HealthCheckTimeout
Maximum time in seconds to wait for service health check during startup.
 
.PARAMETER HealthCheckInterval
Interval in seconds between health check attempts during service startup.
 
.PARAMETER ImageName
Custom Docker image name to use for face recognition processing.
 
.PARAMETER ConfidenceThreshold
Minimum confidence threshold (0.0-1.0) for object detection. Objects with
confidence below this threshold will be filtered out. Default is 0.5.
 
.PARAMETER Language
Specifies the language for generated descriptions and keywords. Defaults to
English.
 
.PARAMETER Model
Name or partial path of the model to initialize.
 
.PARAMETER HuggingFaceIdentifier
The LM-Studio model to use.

Api endpoint url, defaults to http://localhost:1234/v1/chat/completions.
 
.PARAMETER ApiKey
The API key to use for the request.
 
.PARAMETER TimeoutSeconds
Timeout in seconds for the request, defaults to 24 hours.
 
.PARAMETER MaxToken
Maximum tokens in response (-1 for default).
 
.PARAMETER TTLSeconds
Set a TTL (in seconds) for models loaded via API.
 
.PARAMETER FacesDirectory
The directory containing face images organized by person folders. If not
specified, uses the configured faces directory preference.
 
.PARAMETER PreferencesDatabasePath
Database path for preference data files.
 
.PARAMETER RetryFailed
Specifies whether to retry previously failed image keyword updates. When
enabled, the function will attempt to process images that failed in previous
runs.
 
.PARAMETER NoRecurse
Dont't recurse into subdirectories when processing images.
 
.PARAMETER RedoAll
Forces reprocessing of all images regardless of previous processing status.
 
.PARAMETER NoLMStudioInitialize
Skip LM-Studio initialization when already called by parent function to avoid
duplicate container setup.
 
.PARAMETER NoDockerInitialize
Skip Docker initialization when already called by parent function to avoid
duplicate container setup.
 
.PARAMETER Force
Force rebuild of Docker container and remove existing data for clean start.
And force restart of LMStudio.
 
.PARAMETER UseGPU
Use GPU-accelerated version for faster processing (requires NVIDIA GPU).
 
.PARAMETER ShowWindow
Show Docker + LM Studio window during initialization.
 
.PARAMETER PassThru
PassThru to return structured objects instead of outputting to console.
 
.PARAMETER AutoUpdateFaces
Detects changes in the faces directory and re-registers faces if needed.
 
.PARAMETER SessionOnly
Use alternative settings stored in session for AI preferences like Language,
Image collections, etc.
 
.PARAMETER ClearSession
Clear alternative settings stored in session for AI preferences like Language,
Image collections, etc.
 
.PARAMETER SkipSession
Dont use alternative settings stored in session for AI preferences like
Language, Image collections, etc.
 
.PARAMETER Monitor
Monitor selection for window positioning: 0=primary, 1+=specific monitor,
-1=current, -2=secondary.
 
.PARAMETER NoBorders
Removes window borders and title bar for a cleaner appearance.
 
.PARAMETER Width
Window width in pixels for positioning applications.
 
.PARAMETER Height
Window height in pixels for positioning applications.
 
.PARAMETER X
Window horizontal position for positioning applications.
 
.PARAMETER Y
Window vertical position for positioning applications.
 
.PARAMETER Left
Places window on left half of screen.
 
.PARAMETER Right
Places window on right half of screen.
 
.PARAMETER Top
Places window on top half of screen.
 
.PARAMETER Bottom
Places window on bottom half of screen.
 
.PARAMETER Centered
Centers window on screen.
 
.PARAMETER Fullscreen
Maximizes window to fill entire screen.
 
.PARAMETER RestoreFocus
Returns focus to PowerShell window after positioning.
 
.PARAMETER SideBySide
Places windows side by side with PowerShell on the same monitor.
 
.PARAMETER FocusWindow
Focus the window after positioning.
 
.PARAMETER SetForeground
Set the window to foreground after positioning.
 
.PARAMETER Maximize
Maximize the window after positioning.
 
.PARAMETER KeysToSend
Keystrokes to send to the window after positioning.
