Auto Contrast
The
Auto Contrast node in AugeLab Studio applies automatic contrast adjustment to an input image using the histogram clip algorithm. This algorithm adjusts the contrast of the image by redistributing pixel values within a specified threshold.The
Auto Contrast node enhances the contrast of an input image by redistributing pixel values based on the histogram of the image. It applies the histogram clip algorithm to automatically adjust the contrast.- Node Title: Auto Contrast
- Node ID: OP_NODE_AUTO_CONTRAST
The
Auto Contrast node has the following input socket:- Image: The input image to apply automatic contrast adjustment. Connect an image to this socket.
The
Auto Contrast node has the following output socket:- Output Image: The output image with the automatic contrast adjustment applied.
The
Auto Contrast node provides a slider labeled Threshold that allows you to adjust the contrast enhancement. The threshold value determines the percentage of pixel values to clip from both ends of the histogram.- 1.Drag and drop the
Auto Contrastnode from the node library onto the canvas in AugeLab Studio. - 2.Connect the input image to the Image input socket of the
Auto Contrastnode. - 3.Adjust the Threshold slider to set the percentage of pixel values to clip from both ends of the histogram. Higher values result in a more pronounced contrast enhancement.
- 4.Run the pipeline.
- 5.The
Auto Contrastnode will apply automatic contrast adjustment to the input image. - 6.The output image with the automatic contrast adjustment applied will be available at the Output Image output socket.
- The
Auto Contrastnode uses the histogram clip algorithm to adjust the contrast of the input image. The algorithm redistributes pixel values within the specified threshold, resulting in enhanced contrast. - The input image can be grayscale or color. If the input image is color, the algorithm is applied to each channel independently.
- Adjust the Threshold slider to control the amount of contrast enhancement. Higher values clip a larger percentage of pixel values from both ends of the histogram, resulting in a more pronounced contrast enhancement.
- Experiment with different threshold values to achieve the desired contrast enhancement effect.
That concludes the documentation for the
Auto Contrast node in AugeLab Studio. This node provides an easy way to apply automatic contrast adjustment to images using the histogram clip algorithm.
