Features

• Animation: non-linear, edge-preserving, and noise-reducing smoothing filter.
• Bilateral Blur: non-linear, edge-preserving, and noise-reducing smoothing filter.
• Color management: accurate color management with color profiles or in lieu of-- built-in gamma compression or expansion as demanded by the colorspace.
• Color thresholding force all pixels in the color range to white otherwise black.
• Command-line processing utilize ImageMagick from the command-line.
• Complex text layout bidirectional text support and shaping.
• Composite: overlap one image over another.
• Connected component labeling: uniquely label connected regions in an image.
• Convex hull smallest area convex polygon containing the image foreground objects. In addition, the minimum bounding box and unrotate angle are also generated.
• Decorate: add a border or frame to an image.
• Delineate image features: Canny edge detection, mean-shift, Hough lines.
• Discrete Fourier transform: implements the forward and inverse DFT.
• Distributed pixel cache: offload intermediate pixel storage to one or more remote servers.
• Draw: add shapes or text to an image.
• Encipher or decipher an image: convert ordinary images into unintelligible gibberish and back again.
• Format conversion: convert an image from one format to another (e.g. PNG to JPEG).
• Generalized pixel distortion: correct for, or induce image distortions including perspective.
• Heterogeneous distributed processing: certain algorithms are OpenCL-enabled to take advantage of speed-ups offered by executing in concert across heterogeneous platforms consisting of CPUs, GPUs, and other processors.
• High dynamic-range images: accurately represent the wide range of intensity levels found in real scenes ranging from the brightest direct sunlight to the deepest darkest shadows.
• Histogram equalization use adaptive histogram equalization to improve contrast in images.
• Image cache: secure methods and tools to cache images, image sequences, video, audio or metadata in a local folder.
• Image calculator: apply a mathematical expression to an image or image channels.
• Image gradients: create a gradual blend of one color whose shape is horizontal, vertical, circular, or elliptical.
• Image identification: describe the format and attributes of an image.
• ImageMagick on the iPhone: convert, edit, or compose images on your iPhone.
• Large image support: read, process, or write mega-, giga-, or tera-pixel image sizes.
• Montage: juxtapose image thumbnails on an image canvas.
• Morphology of shapes: extract features, describe shapes and recognize patterns in images.
• Motion picture support: read and write the common image formats used in digital film work.
• Multispectral imagery: support multispectral imagery up to 64 bands.
• Noise and color reduction Kuwahara Filter, mean-shift.
• Perceptual hash: maps visually identical images to the same or similar hash-- useful in image retrieval, authentication, indexing, or copy detection as well as digital watermarking.
• Special effects: blur, sharpen, threshold, or tint an image.
• Text & comments: insert descriptive or artistic text in an image.
• Threads of execution support: ImageMagick is thread safe and most internal algorithms are OpenMP-enabled to take advantage of speed-ups offered by multicore processor chips.
• Transform: resize, rotate, deskew, crop, flip or trim an image.
• Transparency: render portions of an image invisible.
• Virtual pixel support: convenient access to pixels outside the image region.
