This example shows how to align or register two images that differ by a rotation and a scale change. You can calculate the rotation angle and scale factor and transform the distorted image to recover the original image.

This example demonstrates how to automatically determine the geometric transformation between two images. Specifically, when one image is distorted in relation to another due to rotation and scaling, the functions detectSURFFeatures and estimateGeometricTransform2D can be employed to identify the rotation angle and scale factor. Subsequently ...

May 22, 2019 · Image resize changes the size of an image. There are two ways of using the imresize column. if the input image has more than two dimensions imresize only resizes the first two dimensions. J = imresize(I, scale) : The method takes the input image I as input and a scaling factor and scales the input image with that factor.

This repository includes sample MATLAB scripts to perform essential tasks, including scaling, binarization, applying filters, analyzing histograms, and more. These examples are useful for students, researchers, and professionals interested in digital image processing.

Jun 24, 2012 · If you look at the histogram of the image using hist(myImg(:)) you can tell how must of the allowed values the image is actually using. In a normalized image, the smallest value will be 0 and the largest will be 1 (or whatever range you use).

Figure 6 shows the image processing procedure using Matlab to detect the breakup length and the spray angle. To classify the pixel as dynamic or stationary, a criterion named the "deviation...

A minimalist Matlab implementation of the image basic processign functions like: rotating an image and scaling an image. The project works for both greyscaled images and RBG images. Project tries to solve those problems using 3 different …

Sep 15, 2024 · The imresize function is a commonly used tool in MATLAB for image scaling. It accepts an input image and a scale factor as parameters and returns a resized image. The scale factor is a number that represents the scaling ratio for each dimension of the image. For example, an image with a scale factor of 2 will be enlarged to twice its original size.

Perform necessary scaling to convert between image classes and types. detects input data class and scales to allow recognition of data as valid image data. takes arbitrary double array input and scales to range [0,1]. converts X input to class double in range [0,1] unless input is of class double, no effect.

Oct 14, 2013 · This function takes an image or matrix and rotate it by theta (radian, rigid motion) The image could also be enlarged or shrinked by an optional scaling factor. img: input image (or or a 2D Matrix) dtheta: the amount of rotation in radian scale: a scalar number that scales the image (default=1) interpMethod:
