Image Resizing in Matlab
B = imresize(A,m,method) returns an image that is m times the size of A. If m is between 0 and 1.0, B is smaller than A. If m is greater than 1.0, B is larger than A. B = imresize(A,[mrows ncols],method) returns an image of size [mrows ncols]. If the specified size does not produce the same aspect ratio as the input image has, the output image.

Specify the desired height of the image. targetHeight = 300; Resize the image, specifying the output size of the image. Because the second element of targetSize is NaN, imresize automatically calculates the number of rows needed to preserve the aspect ratio. targetSize = [targetHeight NaN]; J = imresize (I,targetSize); [h,w,~] = size (J) h = 300.

You want to resize an image to be as large as possible without the width and height exceeding a maximum value. Start by reading and displaying an image. I = imread ( "lighthouse.png" ); imshow (I) Get the size of the image. The aspect ratio of this image is 3:4, meaning that the width is 3/4 of the height. [heightI,widthI,~] = size (I) heightI.

Image Resize using imresize (): 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.

However, you need to be cognizant that MATLAB performs the resizing with anti-aliasing enabled by default. I'm not sure what scipy.misc.resize does here but I'll bet that there is no anti-aliasing enabled. Edit - November 23rd, 2016. As noted by Eric in his comments below, if you pre-cast the image to the desired type, you will get the expected.

Region of interest, specified as [x y width height], where [x y] are the coordinates for the upper-left corner of the region.width and height specify the width and the height of the region, respectively.. If you specify an input value to the ROI port, the Resize block applies the transformation only to a specified region in the input image.

Resize the image, using the imresize function. In this example, you specify a magnification factor. To enlarge an image, specify a magnification factor greater than 1. magnificationFactor = 1.25; J = imresize (I,magnificationFactor); Display the original and enlarged image in a montage. imshowpair (I,J,method= "montage")
How to Resize the Image Using MATLAB ? YouTube
The Image Processing Toolbox software available in MATLAB supports several operations that can be performed on images. The function of resizing images is one of those functionalities. Resizing any 2D image in MATLAB can be performed using the resize procedure, whereas imresize3() is used for resizing 3-D volumetric intensity images.

Read an RGB image into the workspace. RGB = imread ( 'peppers.png' ); Resize the RGB image to have 64 rows. imresize calculates the number of columns automatically. RGB2 = imresize (RGB, [64 NaN]); Get the size of the resized image. sz = size (RGB2) sz = 1×3 64 86 3. Display the original image and the resized image.

Output size, specified as a row vector of integers. Each element of sz indicates the size of the corresponding dimension in B.You must specify sz so that the number of elements in A and B are the same. That is, prod(sz) must be the same as numel(A). Beyond the second dimension, the output, B, does not reflect trailing dimensions with a size of 1.For example, reshape(A,[3,2,1,1]) produces a 3.

Resizing an Image . In MATLAB manually resize of an image, first read the image to be resized and then apply resizing operation on the image. Example. Aim (1): To resize an image in MATLAB. Program (1):
How to Resize the Image Using MATLAB ? YouTube
Description. B = resize (A,m) resizes A to size m by adding elements to or removing elements from the trailing side of A. For example, for a scalar size m: If A is a vector, then resize (A,m) pads or trims A to length m. If A is a matrix, table, or timetable, then resize (A,m) pads or trims A to have m rows.

B = imresize (A,scale) returns image B that is scale times the size of image A. The input image A can be a grayscale, RGB, binary, or categorical image. If A has more than two dimensions, then imresize only resizes the first two dimensions. If scale is between 0 and 1, then B is smaller than A. If scale is greater than 1, then B is larger than A.

Here's how you can write your function, using INTERP2 and generalizing for a 2-D grayscale or 3-D RGB image of any type: function pic_new = scale_image (pic,scale_zoom) oldSize = size (pic); %# Old image size newSize = max (floor (scale_zoom.*oldSize (1:2)),1); %# New image size newX = ( (1:newSize (2))-0.5)./scale_zoom+0.5; %# New image pixel.
