What are the best techniques for digitally restoring an old photo of a loved one to its original glory?

**Digital noise reduction**: Most photo restoration tools use wavelet denoising algorithms to reduce digital noise in old photos, making them appear sharper and more vivid.

**Image decomposition**: Restoration tools often decompose images into three components: luminance (brightness), chrominance (color), and texture, to repair each aspect separately.

**Frequency domain analysis**: Some tools analyze images in the frequency domain to separate signal from noise, allowing for more effective noise reduction and image sharpening.

**Machine learning-based inpainting**: Advanced restoration tools use machine learning algorithms to fill in missing or damaged areas of an image, often using contextual information from surrounding pixels.

**Colorization**: Many tools use colorization algorithms to automatically add color to black and white photos, taking into account the original hues and tones of the scene.

**Artifact removal**: Advanced tools can remove artifacts such as water spots, tears, and scratches from old photos, improving overall image quality.

**Automatic HDR**: Some restoration tools automatically create high dynamic range (HDR) images from old photos, enhancing contrast and color accuracy.

**Local tone mapping**: Some tools apply local tone mapping to balance contrast and color in old photos, making them appear more natural.

**Super-resolution**: Advanced restoration tools can upscale low-resolution images using super-resolution algorithms, making them appear sharper and more detailed.

**Image segmentation**: Some tools segment old photos into regions of interest, applying targeted repairs to each area separately.

**Texture analysis**: Advanced tools analyze textures in old photos to separate genuine image content from noise and artifacts.

**Chroma subsampling**: Some tools use chroma subsampling to reduce color data in old photos, allowing for more efficient compression and improved image quality.

**Non-linear filtering**: Advanced restoration tools use non-linear filters to remove noise and artifacts from old photos, preserving image details and textures.

**Depth from focus**: Some tools estimate depth maps from old photos, allowing for more accurate repairs and restorations.

**Meta-data analysis**: Advanced tools analyze EXIF metadata from old photos to determine optimal restoration settings and parameters.
