About this app

GalileoSharp brings professional-grade image sharpening to your Android device — the same class of algorithms used by NASA and astrophotographers worldwide.

FIVE SCIENTIFIC ALGORITHMS:

🔬 Unsharp Mask — The gold standard. Fine-tune amount, radius, threshold, and multi-pass Gaussian blur. Supports luminance-only mode and highlight protection.

⚡ Laplacian Sharpening — Edge-detection sharpening with selectable kernels: 4-connected, 8-connected, and Difference of Gaussians (DoG). Includes noise gate.

🌊 Fourier Domain — Frequency-space sharpening with Ideal, Gaussian, and Butterworth filter profiles. Control frequency radius and filter order.

🔭 Richardson-Lucy Deconvolution — Iterative blind deconvolution used in Hubble Space Telescope image restoration. Gaussian, Disk, or Motion PSF types.

〰️ Wavelet Sharpening — Multi-scale detail enhancement with independent boosts for fine, medium, and coarse detail levels.

FEATURES:
• Before/After split-view with draggable divider
• Batch processing — sharpen entire folders at once
• Saves to Downloads in full quality
• Works fully offline — no cloud, no uploads
• Dark room aesthetic — designed for serious image work

Perfect for astrophotography, old photo restoration, landscape photography, and scientific imaging.
