I'm trying to generate "crumpled" images using images obtained from a flatbed bed scanner. By following the method described in the paper[Link] in the section 3.1. I've written the code g...

I got camera intrinsic matrix and distortion parameters using camera calibration. The unit of the focal length is pixels, i guess. Then, how can i calculate field of view (along y) ? Is this f...

I am writing a simple transformation for a dataset which contains many pairs of images. As a data augmentation, I want to apply some random transformation for each pair but the images in that pair ...

I want to detect only green objects from an image captured in a natural environment. How can I define it? Because in here I want to pass the threshold value, let's say 'x'. By using this x, I want ...

Background I have a bunch of RGBA images. Imagine icons, logos or similar images that I would like to display. These images can be of any color. Please also note that the images are RGBA, so they h...

I am trying to detect if the picture(black and white sketch) is colored or not in the room conditions by a mobile camera. I have been able to get this result using following code Mat dest...

I am working on a project which is image searching engine. The logic behind is that there will be some images stored in a database and the user will input a new image and it will be matched w...

I want to extract Hebrew text from an image. I've tried using pytesseract, but it gets some letters confused (for example ' instead of י or נ instead of כ) I tried doing some manipulations on the...

This is a truck container image but from the top view. First, I need to find the rectangle and know each corner position. The goal is to know the dimension of the container.

I'm looking for a proper solution how to count particles and measure their sizes in this image: In the end I have to obtain the lists of particles' coordinates and area squares. After some search ...

I'm a beginner in python and currently studying QR code detection and decoding. I'm having a hard time rotating the detected QR code to the right position. I already used minAreaRect() to rotate my...

In testing an object detection algorithm in large images, we check our detected bounding boxes against the coordinates given for the ground truth rectangles. According to the Pascal VOC challenges...

I am creating a sign language detection application in Armenian. However, the Armenian letters don't show when I am signing but do show in my console/terminal. What am I doing wrong with my code th...

I have the following image of a lego board with some bricks on it Now I am trying to detect the thick black lines (connecting the white squares) with OpenCV. I have already experimented a lot with...

I have images with white background and simple shapes in them (each image has one shape). I want to determine if a certain point (x,y) is inside the shape or not. How can I do that with opencv?

I want to remove the background, and draw the outline of the box shown in the image(there are multiple such images with a similar background) . I tried multiple methods in OpenCV, however I am una...

I am trying to implement the algorithm found here in python with OpenCV. I am trying to implement the part of the algorithm that remove irrelevant edge boundaries based on the number of interior bo...

I am planning to split the questions from this PDF document. The challenge is that the questions are not orderly spaced. For example the first question occupies an entire page, second also the same...

I have a stationary camera which takes photos rapidly of the continuosly moving product but in a fixed position just of the same angle (translation perspective). I need to stitch all images into a ...
