Consider this as a beginner’s tutorial to Matlab image processing. Read the documentation of the commands used and try and understand what they are doing and why. 1. Read the image Use imread to read the image into a 3D…

## [Solved] How can I detect the dimensions of an object under an angle in this picture in MATLAB? [closed]

Introduction This question is about how to detect the dimensions of an object under an angle in a picture using MATLAB. MATLAB is a powerful tool for image processing and can be used to detect the dimensions of an object…

## [Solved] How to get an image of each letter from image with text [closed]

As a basic technique, use binarization and connected component analysis. This will give you “blobs” corresponding to the individual characters and you can get their bounding boxes. You will face extra difficulties: some characters can touch and form a single…

## [Solved] What is the best way of learning Digital Image processing? [closed]

The only problem with MATLAB, for a beginner, is that it is really expensive. Some universities buy it without the Image Processing Toolbox, in which case it is not so useful. Octave is well supported by the open source community,…

## [Solved] Why is the output of `conv2()` is divided by `sz^2`?

Note that conv2(double(im(:,:,q)),mask,’same’)./sz^2 is the same as conv2(double(im(:,:,q)),mask./sz^2,’same’) This is because the convolution and the multiplication commute. Thus, the convolution operation computes a local mean. Without the division, it would be a local sum. 0 solved Why is the output…

## [Solved] Pyramidal Histogram Of Oriented Gradients – Trilinear interpolation

Short answer is: you can’t apply Trilinear Inerpolation. Let’s start with 2x2x2 blocks. Each block, is represented by it’s centre pixel ( 1,2,3,4 in ugly yellow on my sketch). Each pixel is located at the corner of a cell. A…

## [Solved] png format images are not stored in my server [closed]

I tried to make your code a bit more clear, and help you find what is happening on your code, use the var_dump() to see the values. Of course all the \$_REQUEST and \$_SERVER should be correct. // initialize variables…

## [Solved] face detection with svm and feature extraction using matlab [closed]

For starters, try detecting faces using vision.CascadeObjectDetector in the Computer Vision System Toolbox. If you have to roll your own, then take a look at this example, showing how to train a classifier to recognize digits using HOG features and…

## [Solved] Scala in image processing [closed]

## [Solved] How can I apply a ring-shaped median filter to an image in matlab? [closed]

you can use ordfilt2 . For example, if your “ring” is just defined by: ring= fspecial(‘gaussian’,21,1) ring = ring>eps & ring<1e-9 then: order=sum(ring(:))/2; B = ordfilt2(A,order,ring); replaces each element in A by the order-th element in the sorted set of…

## [Solved] OCR – How to recognize numbers inside square boxes using python?

the code below for me is doing decent job but it’s hyper parameter sensitive : import cv2 import imutils import numpy as np import matplotlib.pyplot as plt from matplotlib import pyplot as plt def square_number_box_denoiser(image_path=””,is_resize = False, resize_width = 768):…

## [Solved] Extract a periodic pattern from an image in Matlab

What you said, is quite a project, not a question. I’d rather to study more about the similar projects and ask about some details in here. Although I could give you some hints: 1-Do a suitable thresholding on your image,…

## [Solved] please guide me to split the image

You can use mat2cell to split the image into as many splits as you want: img = imread(”); [h w c] = size(img); numSplits = 3; % how many splits you want sw = floor(w/numSplits); % width of split widths…
