Semantic segmentation, is one of the most used techniques to create the training data for the deep neural network. Types of neighborhoods Neighborhood operations play a key role in modern digital image processing. A binary image is referred to as a 1-bit image because it takes only 1 binary digit to represent each Image sharpening and restoration- so that a better graphic/photo can be created Image retrieval- searching for a desired image Image recognition- the objects in a graphic/photo can be distinguished Types of processing an image There are 2 methods typically used: Analog Digital C. A. Bouman: Digital Image Processing - April 17, 2013 3 Two Types of Source (Image) Coding •Lossless coding (entropy coding) – Data can be decoded to form exactly the same bits – Used in “zip” – Can only achieve moderate compression (e.g. Angela Farrer Different types of image processing applications include those used in the fields of medicine, digital art, meteorology, law enforcement and more. “dtypes”. It is primarily beneficial for applications like object recognition or image compression because, for these types of applications, it is expensive to process the whole image. In this work, we propose a method designed to reduce the Gaussian, the impulsive and speckle noise and combined noise. It is converting a graphic or photo in digital form and performing some steps and procedures so that the said photo/graphic can be enhanced or you can extract information from it. There are two RGB pixel types in dlib, rgb_pixel and bgr_pixel. Types of Digital Images The images types we will consider are: 1) binary, 2) gray-scale, 3) color, and 4) multispectral. Based on the image segmentation approaches and the type of processing that is needed to be incorporated to attain a goal, we have the following techniques for image segmentation. Transformation is one such type of image processing technique. A large number of image processing techniques (filters) have been proposed to remove noise. I'm declaring an interface which will contains image also. Smoothing also called blurring . There are different types of noises, and they require different filters to remove them; some of them are. The digital image processing is a special type of processor which is used in every electronic device whether it be CD, mobile phones, battlefields, satellites, medical, and voice detection machines etc. d) bicubic interpolation.

Signal processing techniques can be used to improve transmission, storage efficiency and subjective quality and to also emphasize or detect components of interest in a measured signal. From a grayscale image, thresholding can be used to create binary images. For Image Processing Toolbox 3 in 2001, we stopped adding data type support piecemeal and instead added support for all the data types in MATLAB at the time. Binary Image: A binary image has only two possible gray values or intensities 0 and 255, there are no intermediate values. It is a type of signal processing in which input is an image and output may be image or characteristics/features associated with that image. In image enhancement, an image is manipulated, mostly by heuristic techniques, so that a human viewer can extract useful information from it. This is very effective in processes like image recognition and facial recognition. The Octave-forge Image package provides functions for processing images.
