ComfyUI Node: Adjust Neck v4.7.3

Adjust Neck v4.7.3:

The tri3d-HistogramEqualization node is designed to enhance the contrast of an image by equalizing its histogram. This process redistributes the intensity values of the image, making the histogram of the output image more uniform. The primary benefit of this node is its ability to improve the visibility of details in images, especially in cases where the image is too dark or too bright. By adjusting the distribution of pixel intensities, it can bring out hidden features and enhance the overall quality of the image. The node provides a simple interface to apply this technique, allowing you to control the degree of equalization through a strength parameter. This makes it a valuable tool for AI artists looking to enhance their images without delving into complex image processing techniques.

Adjust Neck v4.7.3 Input Parameters:

image

The image parameter is the input image that you want to process. It is expected to be in the form of an IMAGE type, which typically means a tensor representation of the image. This parameter is crucial as it serves as the base for the histogram equalization process. The quality and characteristics of the input image will directly affect the results of the equalization.

strength

The strength parameter is a FLOAT value that determines the intensity of the histogram equalization effect applied to the image. It ranges from 0.0 to 1.0, with a default value of 1.0. A strength of 0.0 means no equalization is applied, while a strength of 1.0 applies full equalization. Adjusting this parameter allows you to blend the original image with the equalized version, providing flexibility in achieving the desired level of contrast enhancement.

Adjust Neck v4.7.3 Output Parameters:

IMAGE

The output of the tri3d-HistogramEqualization node is an IMAGE type, which is the processed image with enhanced contrast. This output image has undergone histogram equalization, resulting in a more balanced distribution of pixel intensities. The output is particularly useful for improving the visibility of details in images that suffer from poor contrast, making it easier to discern features that were previously obscured.

Adjust Neck v4.7.3 Usage Tips:

• To achieve subtle contrast enhancements, start with a lower strength value and gradually increase it until you reach the desired effect.
• Use this node to preprocess images before applying other image processing techniques, as it can help reveal details that might be important for subsequent operations.

Adjust Neck v4.7.3 Common Errors and Solutions:

Image tensor conversion error

• Explanation: This error may occur if the input image is not in the expected tensor format.
• Solution: Ensure that the input image is correctly formatted as a tensor before passing it to the node.

Strength value out of range

• Explanation: This error happens when the strength parameter is set outside its allowed range of 0.0 to 1.0.
• Solution: Adjust the strength parameter to be within the specified range to avoid this error.
