Tool usage guide
The Image Dilate tool performs a morphological operation that expands foreground objects in binary images, making them thicker or more prominent by adding pixels to their boundaries.
Background
A collection of scanned historical documents contains faint, broken text characters that are difficult to read.
Problem
The text is too thin and fragmented for OCR software to recognize accurately.
How to use
Upload the binary scan and set the iterations to 2 to thicken the character strokes.
iterations: 2Outcome
The characters appear bolder and more connected, significantly improving OCR recognition rates.
Background
A binary mask generated by a segmentation model has small gaps within the detected object boundaries.
Problem
The gaps prevent the mask from covering the entire object area.
How to use
Upload the mask image and apply 1 iteration of dilation to close the gaps.
iterations: 1Dilation is a morphological operation that adds pixels to the boundaries of objects in an image, effectively expanding the foreground.
This tool is designed for binary images (black and white), where the foreground is clearly distinguished from the background.
The iterations setting determines how many times the dilation process is applied; higher values result in more significant expansion.
Yes, the maximum file size for uploads is 10 MB.
No, this tool processes one image file at a time.
Outcome
The mask now fully encompasses the object, providing a solid silhouette for further analysis.
