海外TECH	DEV Community	Creating Various Filters With OpenCV/Python	https://dev.to/ethand91/creating-various-filters-with-opencvpython-3077	Creating Various Filters With OpenCV Python IntroductionHello I recently decided to add more filters to my previous cartoon filter example which can be found here This post continues from the above post so I won t be going over creating the virtual environment etc Well then lets add some more cool filters HDR FilterThe HDR effect filter is simple to implement we just use the detailEnhance method def HD image hdrImage cv detailEnhance image sigma s sigma r return hdrImagesigma s controls how much the image is smoothed and sigma r is important to preserve edges while smoothing the image Pencil Sketch GreyScale Color FilterThis is another easy to implement filter as opencv already has a method that can do this for us This method returns both the greyscale image and the color image here I am returning the color version but feel free to try out the greyscale image too def pencil image sk gray skColor cv pencilSketch image sigma s sigma r shade factor return skColor Sepia FilterThe sepia filter lets us apply a brown calm effect to images To do this we convert to float to prevent loss transform the image and then finally normalizing the values def sepia image Convert to float to prevent loss sepiaImage np array image dtype np float sepiaImage cv transform sepiaImage np matrix sepiaImage np where sepiaImage gt sepiaImage np array sepiaImage dtype np uint return sepiaImage Sharpen FilterTo sharpen the image we will use the filterD method and apply the following kernel def sharpen image kernel np array sharpenedImage cv filterD image kernel return sharpenedImage Brightness FilterTo adjust the image s brightness we will use the convertScaleAbs method def brightness image betaValue brightImage cv convertScaleAbs image beta betaValue return brightImageWe can also use this filter to make the image darker by passing a negative value to beta Greyscale FilterGreyscale filter is another easy filter to implement wi just use the cvtColor method def grayScale image grayImage cv cvtColor image cv COLOR BGRGRAY return grayImage Invert FilterAnother easy filter to implement we just invert the pixel values using the bitwise not method def invert image invertedImage cv bitwise not image return invertedImage Saving the imagesOnce we have all the filtering methods defined it would be a shame not to use them Edit the main method to include the following cartoonImage cartoonize image invertedImage invert image grayImage grayScale image brightImage brightness image darkerImage brightness image sharperImage sharpen image sepiaImage sepia image pencilImage pencil image hdrImage HD image Finally we can write the output to file with the following append them to the main method cv imwrite output jpg cartoonImage cv imwrite inverted jpg invertedImage cv imwrite grayscale jpg grayImage cv imwrite brighter jpg brightImage cv imwrite darker jpg darkerImage cv imwrite sharper jpg sharperImage cv imwrite sepia jpg sepiaImage cv imwrite pencil jpg pencilImage cv imwrite hdrImage jpg hdrImage Done Feel free to change the values etc to see what different effects you can make ConclusionHere I have shown how to apply various filters to an image using opencv s methods it wasn t too hard to implement I will make another post if I manage to find more interesting fun filters 🥸The repo can be found here Like me work I post about a variety of topics if you would like to see more please like and follow me Also I love coffee	2022-05-06 10:03:00
