"Digital image processing is the use of a digital computer to process digital images through an algorithm."
The manipulation of digital images using mathematical algorithms and techniques.
Digital image fundamentals: This includes topics such as pixel resolution, color depth, image formats, image compression, image acquisition, and digital image enhancement methods.
Image filtering and enhancement: This covers methods for improving the quality of images, such as sharpening, smoothing, noise reduction, contrast enhancement, and color normalization.
Image segmentation and feature extraction: This involves methods for separating an image into meaningful regions and identifying important features within those regions, such as edges, textures, patterns, and shapes.
Multispectral and hyperspectral imaging: This includes techniques for acquiring and processing images with multiple channels or bands of data, such as infrared, ultraviolet, or radar images, and using this data to extract information about the composition and properties of objects in the images.
Geometric processing and mapping: This covers methods for correcting distortions and aligning images to a common coordinate system, as well as techniques for creating maps, mosaics, and 3D models from image data.
Machine learning and computer vision: This involves using statistical and computational methods to automatically extract information from images, such as detecting objects, recognizing patterns, and classifying images.
Data visualization and interpretation: This includes techniques for displaying and communicating image data in a meaningful way, such as using color maps, histograms, scatterplots, and other visualizations to highlight patterns and trends.
Data processing and management: This covers tools and techniques for storing, retrieving, and processing large volumes of image data, such as databases, distributed computing frameworks, and cloud computing platforms.
Software tools and libraries: This includes popular software packages and libraries that are commonly used in image processing and astrogeology, such as MATLAB, Python, ENVI, IDL, and GDAL.
Applications in astrogeology: Finally, it is important to understand the specific applications and challenges of image processing in the field of astrogeology, such as analyzing images of planetary surfaces, identifying geological features and processes, and understanding the interactions between planetary geology, climate, and astrobiology.
Image Enhancement: Improving the quality and clarity of an image by altering the brightness, contrast and sharpness.
Noise reduction: Processing techniques that remove unwanted noise in an image caused by random fluctuations in pixel values.
Image restoration: Reconstructing an image that has been degraded by distortions such as blur, haze, or distortion.
Image segmentation: Dividing an image into different regions or objects based on their characteristics or features.
Object recognition: Identifying and categorizing objects in an image by their features, shape or size.
Compression: Reducing the size of an image while retaining important information.
Image registration: Aligning multiple images of the same object to create a composite image.
Remote sensing: Analyzing images of earth from space to gather information about the Earth’s surface.
3D modelling: Creating a 3D representation of an object or terrain using images.
Machine learning: Using algorithms and statistical models to enable a computer to learn from and make predictions on image data.
Image analysis: Extracting useful information from an image for scientific, medical or engineering purposes.
Data fusion: Combining different types of data from various sensors to enhance the accuracy of image analysis.
Geospatial analysis: Analyzing and interpreting geographic data from earth photography and satellite imagery.
Radiometric analysis: Measuring and analyzing the amount of radiation reflected or emitted from different surfaces using photographic data.
