Name	Type	Required	Description
imageFile	fileupload required	Yes	Upload any image file (JPEG, PNG, WebP, GIF, BMP, TIFF) to reduce noise and improve image quality
algorithm	select	No	Choose the denoising algorithm. Median works well for salt & pepper noise, Gaussian for random noise
strength	range	No	Strength of noise reduction. Higher values remove more noise but may blur details
kernelSize	range	No	Size of the filter kernel (must be odd). Larger kernels remove more noise but may blur details
iterations	number	No	Number of denoising passes. More iterations = stronger noise reduction
preserveEdges	checkbox	No	Maintain edge detail while removing noise. Recommended for photos with important details
format	select	No	Choose output format or keep original. PNG recommended for maximum quality
quality	number	No	Output quality for lossy formats (JPEG, WebP). Higher = better quality but larger file size
