I have been working on Images for few months for my internship, and recently I have been wondering that is there a mathematical way of resizing the images. This
I am working on Image processing with deep learning and I came on to the topic Error level Analysis which gives/shows the difference in compression level(I'm tr
The code snippet in Python should convert the rgb image to black and white, but only a black image output. I do not know where the problem is (input and output
I am currently working on lines extraction from a binary image. I initially performed a few image processing steps including threshold segmentation and obtained
Hi guys greetings am trying to denoise many several noises with several filters for a research i have, i found a deconvolution wiener filter made by "mr.tranlea
I have a list of points let's say 5 points. I want to crop the area that this polygon is covering from the image. Here, red areas are the points and I want to c
I am new to OpenCV. I have a "simple" image of a stamp that I have already processed a bit, as you can see in the code below. Now I have the problem of cropping
I need to desaturate the background of this kind of images. I thought I can find the largest contour and desaturate everything around. So far I can find the lar
I am working on eigen transformation - texture to detect object from an image. This work was published in ACCV 2006 page number 71. Full pdf is available on cha
I have used the MOTION_HOMOGRAPHY function in OpenCV (python3.6) to register a pair of images, and I am trying to interpret the 3 x 3 warp matrix the function r
I am using this function that I found on the web, its add_speckle() function for adding speckle noise to images : def add_speckle(k,theta,img): gauss = np.
I have the following image I find the contour using contours, hierarchy = cv2.findContours(thresh, cv2.RETR_LIST, cv2.CHAIN_APPROX_NONE) contour = contours[0]
I am trying to do 2D ball stabilization platform which always keeps the ball which is put on the platform, center of the platform (x= 0, y=0). Here is my restri
I'm using OpenCV houghcircles to identify all the circles (both hollow and filled). Follow is my code: import numpy as np import cv2 img = cv2.imread('images/3
I am working on image processing, I have a folder with all of the images that needs to be processed, and I want to save all the processed images to another fold
I want to inject a 2D travelling wave into a sensor system for seismic data analysis. To do this, I inject a 2D sine wave of known parameters (wave numbers (lam
I have a task to load and extract feature embeddings from images. I've working solutions that utilize two different ways of loading the image: tensorflow.keras.
