Computer Vision & Image Processing Tools

Inspect and transform images with browser-based computer vision workflows for edges, histograms, morphology, segmentation, features, geometry, and procedural textures.

• Histogram Analysis. Analyze RGB, grayscale, and cumulative histograms online to inspect exposure, tonal range, and color distribution.
• Blur & Sharpen. Compare Gaussian blur, median filtering, bilateral smoothing, and unsharp masking for denoising and edge-aware sharpening.
• CLAHE Enhance. Boost local contrast with CLAHE (Contrast Limited Adaptive Histogram Equalization). Recover detail in dark or hazy photos.
• Unsharp Mask. Sharpen images using the classic unsharp masking technique. Gaussian blur subtraction with adjustable radius, amount and edge threshold.
• Vignette Effect. Add cinematic vignettes. Darken, lighten or color-tint image edges with smooth radial falloff for moody portraits and posters.
• Pencil Sketch. Convert a photo to a pencil-sketch effect with an invert, blur, and color-dodge workflow. Choose grayscale or color-tinted output.
• Gradient Operators. Compare Sobel, Scharr, Prewitt, and Laplacian gradient operators with direction and output-strength controls.
• Chromatic Aberration. Add cinematic RGB-split / lens chromatic aberration: radial, linear, or zoom mode with adjustable shift and direction.
• Frequency Domain. Inspect DFT magnitude, phase, and centered frequency spectrum for filtering, deblurring, and signal analysis.
• Optical Flow. Analyze frame-to-frame motion with dense optical flow, residual camera compensation, confidence maps, motion trails, masks, direction fields, and vector diagnostics.
• Perspective Transform. Correct perspective distortion with four-point homography to straighten documents, screens, signs, and planar surfaces.
• Image to Normal Map. Turn a texture or height map into a tangent-space normal map with selectable derivative kernels, adjustable depth, and an OpenGL or Direct3D green channel.
• ASCII Art Generator. Render an image as rasterized ASCII-style character art with adjustable width, character density, color mode, contrast, and PNG download.
• Glitch Effect Generator. Add glitch, RGB shift, chromatic aberration, scanlines, and datamosh effects. Retro VHS and deep-fried aesthetic.
• Dithering Tool. Apply Floyd-Steinberg, Atkinson, Bayer, Sierra, or Jarvis-Judice-Ninke dithering with curated retro-inspired palettes and PNG output.
• Halftone Generator. Convert images to raster halftone art with circle, line, square, diamond, cross-hatch, monochrome, and CMYK-style patterns.
• Perlin Noise Generator. Perlin, Simplex, Worley, and value noise with fBm octaves: for game textures, procedural terrain, shader backgrounds.
• Pixel Sort. Sort pixels by brightness, hue, or saturation. The Kim Asendorf viral glitch-art aesthetic.
• Low Poly Generator. Convert images to raster low-poly art with Delaunay triangulation, edge-aware sampling, color averaging, and optional triangle strokes.
• Voronoi Diagram Generator. Create a raster Voronoi mosaic or stippling effect with adjustable sites, relaxation, edges, colors, and PNG download.
