# 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 <a href="#inputs" id="inputs"></a>

`Image Any` First input image to compare.

`Image Any` Second input image to compare.

## 📤 Outputs <a href="#outputs" id="outputs"></a>

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

## 🕹️ Controls <a href="#controls" id="controls"></a>

This function block has no interactive controls.

## 🎨 Features <a href="#features" id="features"></a>

* 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 <a href="#usage" id="usage"></a>

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 <a href="#evaluation" id="evaluation"></a>

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 <a href="#tips-and-tricks" id="tips-and-tricks"></a>

* 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 <a href="#troubleshooting" id="troubleshooting"></a>

* 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.
