Image Color Match

This function block is used to adjust the colors of an input image to match those of a reference image. It utilizes histogram matching to achieve this, allowing for enhanced visual consistency across images.

📥 Inputs

Image RGB The input image that you want to match color with the reference.

Reference Image An image whose color histogram will influence the matching process. If not provided, the input image itself will be used for reference.

📤 Outputs

Image Any The output image will be a modified version of the input image, colored to closely resemble the reference image.

🕹️ Controls

This function block does not have specific controls for user input apart from the inputs mentioned.

🎨 Features

Histogram Matching Utilizes advanced statistical techniques to match the color distribution of the input image to that of the reference image.

Compatibility Works with RGB images, enhancing the visual quality by harmonizing colors.

📝 Usage Instructions

1. Connect Images: Attach the input image to the first socket and, if available, a reference image to the second socket.

2. Evaluate: Run the block to perform color matching. The output will be an image that has its colors adjusted to match the reference.

📊 Evaluation

Upon execution, this function block will output a new image that has undergone color adjustment based on the reference image.

💡 Tips and Tricks

Improving Color Consistency

For best results, use a reference image that closely represents the desired color palette you wish to achieve in the input image.

Multiple Adjustments

You can chain this function block after other image processing blocks like Blur or Auto Contrast to refine the input image before color adjustment.

Testing Different References

Experiment with different reference images to observe how color adjustments can vary greatly based on the histogram of the reference.

🛠️ Troubleshooting

Dimension Mismatch Error

If you encounter an error stating that image sizes must be the same, ensure that both the input and reference images are of identical dimensions. Resize them if necessary.

No Output Image

If the output is not displaying any changes, verify that both images are properly connected and contain valid RGB data.
