Maximum Images

This function block creates a new image by taking the maximum value for each pixel from two input images. Useful for combining images where you want the brightest or strongest response at each pixel.

📥 Inputs

Image Any First input image to compare.

Image Any Second input image to compare.

📤 Outputs

Image Any Resulting image where each pixel is the maximum of the two inputs.

🕹️ Controls

This function block has no interactive controls.

🎨 Features

• Pixel-wise maximum merge of two images.

• Preserves per-channel pixel values (works with multi-channel images).

• Fast operation suitable for combining detection overlays, masks, or image enhancements.

📝 Usage Instructions

1. Connect two image-producing blocks to the two Image Any inputs.

2. Run the scenario; the block outputs a single image where each pixel is the maximum of the corresponding pixels from the inputs.

3. Use the output image for visualization, further processing, or export.

📊 Evaluation

When evaluated, this block compares the two input images pixel-by-pixel and returns the merged image containing the maximum pixel values.

💡 Tips and Tricks

• If the two images have different dimensions, use Image Resize or Image Resizer before this block to match sizes.

• To combine results then visualize them, follow this block with Show Image.

• For the opposite effect (minimum values), use the Minimum Images block.

• Use Apply Mask beforehand to limit merging to specific regions of interest.

• When assembling multi-source visual summaries, consider Image Concatenate or Add Images Weighted after merging to create collages or blended overlays.

• If one image needs padding to align with the other, use Image Padding before merging.

🛠️ Troubleshooting

• Different image sizes: Ensure both inputs share the same width, height, and channel count. Apply Image Resize or Image Resizer if they do not.

• Unexpected colors or channels: Verify both inputs use the same color format (e.g., RGB/BGR) and channel ordering before merging.

• No output or blank image: Confirm upstream blocks are providing valid image data to both inputs; use Show Image on each source to inspect them.
