TeoreX also makes Inpaint, which uses the same sort of code but focuses more I think on removing parts of an image. I see too many technical issues to bother with a single use program, when you really need a multi-functional program such as Photoshop in order to handle all the pieces of the edit, and be able to step through it backwards and forwards, make adjustments at any step, and save each and every edit without starting a new file'įWIW I'd have to say it depends on what you're doing. #25: 'An interesting idea, easily done in Photoshop. Using more traditional clone tools might or might not work better. TO actually accomplish that trash removal you *might* be able to use Inpaint on separate parts of the picture, then put the results back together - whether it was worth the effort or not depends on the texture, lighting, & detail of the house, front yard etc. The trash would be gone, but so would that portion of the house & everything else that was on that now missing slice. the result would be more-or-less like taking a pair of scissors & cutting that slice out of the middle of the photo print, then taping the remaining right & left pieces back together. Lets say you colored the pile of trash red, then narrowed the image by slightly more than the pixel width of that trash. What iResizer does is shrink or stretch an image along the vertical or horizontal axis or both. That would be difficult with most seam carving apps/plugins, & for the most part probably impossible for iResizer to handle on its own. removed trash but rest of photo distorted like a van Gogh although house was green selected.' rotatingImg = cv2.#19: 'I tried to use it on a large photo of a house with a pile of trash in front. Next is to apply the rotation settings that we have defined on the image we read earlier and display the image. Rotate = cv2.getRotationMatrix2D(center,170,1) First we have to determine the center point of rotation which we can determine from the width and height of the image, then determine the degree of rotation of the image and the dimensions of the image output. Image Rotating OpenCVĬhanging the rotation isn’t that difficult either. croppedImg = imgįrom the command above, the crop results from our initial image will appear following the coordinates we specified earlier. First, we determine the initial x coordinate and final x, then determine the initial y coordinate and end y coordinates of the image that has been said to be read earlier. It is not always possible to express the needed information with words and.Ĭropping application to OpenCV is very easy we need to determine where the coordinates of the image to be cropped. In Word documents, you may be introducing various terms, thoughts, or data.

How to Insert a Line in Microsoft Word Documents shape can also be applied to see if the image is grayscale or color image. Please note that if we read the image in grayscale form, the output will only produce rows and columns. The command will output (680, 850, 2) where 680 is the width, and 850 is the height in pixel size, while 2 is the image channel (RGB), or it means that the image has 680 rows and 850 columns. Shape ) to display the dimensions of our source image. Henceforth, we will use the image above in this paper.

Let’s first try reading our image source and displaying it with the functions previously described. As explained earlier in this article, we will learn how to apply resizing, cropping, and rotating techniques to images. Now we can go back to the original topic of basic image manipulation in OpenCV and Python. import cv2įor details on OpenCV Core Image Operations, please read the OpenCV documentation. To write / save images in OpenCV using a function cv2.imwrite()where the first parameter is the name of the new file that we will save and the second parameter is the source of the image itself.

import cv2Ĭv2.imshow('Displaying Images', img) Writing / Saving Images Displaying an Imageĭisplaying an image in OpenCV using a function cv2.imshow()where the first parameter is the window name to display the image and the second parameter is the image itself.

destroyAllWindows ( ) is to close other windows that are currently open. Whiskey ( 0 ) is to keep the window displaying the image. To read images in OpenCV, use a function cv2.imread()where the first parameter is the image file name complete with its extension.
