Std. of Image

This function block calculates the standard deviation of an input image, providing insights into the image's contrast and variation in intensity.

📥 Inputs

Image Any An image from which the standard deviation will be calculated.

📤 Outputs

Standard Deviation A numerical output representing the standard deviation value of pixel intensities in the input image.

🕹️ Controls

Std. Deviation: A label that displays the calculated standard deviation of the input image in real time.

🎨 Features

Simple Calculation Quickly computes the standard deviation without requiring additional configuration or settings.

Real-time Display Updates the displayed value of the standard deviation dynamically when new image data is input.

📝 Usage Instructions

1. Connect Input Image: Link any image to the Image Any input socket.

2. Evaluate Block: Run the block to calculate and retrieve the standard deviation of the connected image.

📊 Evaluation

This function block will output the standard deviation of the pixel intensities in the input image, allowing for assessment of image quality and contrast.

💡 Tips and Tricks

Understanding Standard Deviation

Higher standard deviation indicates a wider range of pixel intensities and more contrast in the image, while a lower value suggests a more uniform or flat image.

Using with Other Analysis Blocks

Combine this block with others like Histogram On Curve for a more comprehensive analysis of the image's pixel intensity distribution or contrast.

🛠️ Troubleshooting

No Output Value

If no output value is displayed, ensure that the input image is properly connected and valid. You can use the Debug Input block to check the data flow.

Unexpected Standard Deviation Value

If the output value seems incorrect, check if the input image is properly formatted and within the expected intensity range (0-255). Use the Image Threshold block for verification.
