Detailed Description

Image processing pipeline for sequential transformation of raw image frames.

The Pipeline class performs a series of configurable image processing steps on raw or pre-processed image data. It is designed to support a complete transformation workflow, from raw sensor input to final output format, with each stage modular and optionally enabled or configured.

Processing Steps:

Unpack (Always Active) – Automatically unpacks packed sensor data formats. This stage is internal and cannot be configured.
Hot Pixel Correction – Identifies and corrects defective pixels (hot pixels).
Binning – Reduces resolution and improves signal-to-noise ratio by combining adjacent pixels.
Decimation – Downscales the image by skipping pixels in a defined pattern.
Mirror – Optionally mirrors the image left-right and/or up-down.
Rotation – Rotates the image by 90, 180, or 270 degrees.
Gain – Applies digital master gain to control image brightness, or digital color gains to adjust white balance.
Debayer (Configured Internally): Converts Bayer pattern raw data to RGB format and expands monochrome images to RGB when a color output format is requested. This behavior is automatically determined based on the input and output pixel formats.
Color Correction – Applies a color correction matrix.
Auto Features – Analyzes the image for the following dynamic adjustments:
- Auto Brightness
- Auto White Balance
- Auto Focus (if supported by the device)
To enable Auto Features, an external module must be provided via:
auto autoFeatureModule = std::make_shared<peak::pipeline::modules::AutoFeatureModule>(remoteDeviceNodeMap);

pipeline.SetAutoFeatureModule(autoFeatureModule);

This module is part of the Auto Feature Library (AFL).
Mono Conversion (Configured Internally) – Converts RGB images to monochrome when a monochrome output format is requested.
Sharpening – Enhances image detail using edge-based sharpening filters.
Gamma – Applies gamma correction to adjust brightness and contrast.
Pixel Format Conversion (Configured Internally) – Converts the processed image to the desired output pixel format.

Smart Pixel Format Configuration Inference:

The pipeline includes built-in logic to automatically configure certain internal stages based on the input and output formats. For example:

If a Bayer image is provided and the output format is RGB, debayering is automatically applied.
If a monochrome image is input and the output format is RGB, the DebayerModule takes over the mono-to-RGB expansion.
If the output format is monochrome, mono conversion is enabled.
If a Bayer pixel format is set as output format, the following features or modules are not processing
- DebayerModule,
- MonoConversionModule,
- SharpeningFeature, and
- GammaFeature.
The PixelFormatConversionModule is responsible for converting to the specified output format. If necessary, the bit depth is reduced during this step.

Use the following method to set the desired final pixel format:

pipeline.SetOutputPixelFormat(PixelFormat::RGB8);

Note: There might be cases where some modules, even though they are enabled, do not apply their configuration, if the pixel format is not supported. Further information can be found in the documentation of the individual "Process" methods for each module.

Configuration:

The pipeline can be configured in two ways:

Module Access: Each configurable processing module can be accessed directly, allowing individual configuration:
pipeline.Gain().SetMaster(1.2f);

pipeline.Gamma().SetValue(2.2f);
Settings File: Load or save all configuration settings:
pipeline.ImportSettingsFromFile("config.json");

pipeline.ExportSettingsToFile("config.json");

This modular and extensible design enables flexible integration into a variety of image processing applications, from camera pipelines to offline image editing.

Conversion modules use pre-allocated internal buffers to accelerate conversions. When the image size or pixel format changes, new buffers are allocated, which may cause the internal buffer pool to grow over time. This function can be used to release unused buffers and reduce memory usage.

Warning: Avoid calling this function too frequently (e.g., after every resize or format change), as it introduces some overhead and may negatively impact performance.

inline

Sets an auto feature module for automatic image adjustments.

These adjustments can include features such as image brightness, white balance, and focus, depending on the capabilities of the provided module.

Note: If there is no auto feature module specified, this step will be skipped during processing.

Parameters

autoFeatureModule The auto feature module.

Since: ids_peak_icv 1.0

Definition at line 930 of file peak_icv_default_pipeline.hpp.

◆ SetOutputPixelFormat()

void SetOutputPixelFormat ( peak::common::PixelFormat format )

inline

Defines the desired pixel format for processed images.

The pipeline will convert images to this format during processing.

Warning: When set to a Bayer format, the ColorCorrection, Gamma and Sharpening features will not process the image because they do not support Bayer formats. This may result in unexpected image quality if these features are enabled.
