Machine Learning is a fast growing field with the potential to transform how humans interact with technology. Using Machine Learning, Machines can learn from data and improve their performance over time, becoming more precise and efficient. However, for ML models to be successful, high-quality decisions must be made throughout the development and deployment processes. Decisions taken during ML development can have a major impact on the accuracy and efficiency of the system. For example, choosing the best ML algorithms and methodologies for a given task might have a considerable impact on system performance. Using the incorrect method or technique ... Read More

In this program, we will calculate the rms (root mean square) of all the pixels in each channel using the Pillow library. There are a total three channels in an image and therefore, we will get a list of three values.Original ImageAlgorithmStep 1: Import the Image and ImageStat libraries. Step 2: Open the image. Step 3: Pass the image to the stat function of the imagestat class. Step 4: Print the root mean square of the pixels.Example Codefrom PIL import Image, ImageStat im = Image.open('image_test.jpg') stat = ImageStat.Stat(im) print(stat.rms)Output[104.86876722259062, 96.13661429330132, 91.8480515464677]

In this program, we will calculate the variance of all the pixels in each channel using the Pillow library. There are a total three channels in an image and therefore, we will get a list of three values.Original ImageAlgorithmStep 1: Import the Image and ImageStat libraries. Step 2: Open the image. Step 3: Pass the image to the stat function of the imagestat class. Step 4: Print the variance of the pixels.Example Codefrom PIL import Image, ImageStat im = Image.open('image_test.jpg') stat = ImageStat.Stat(im) print(stat.var)Output[5221.066590958682, 4388.697801428673, 4291.257706548981]

In this program, we will calculate the standard deviation of all the pixels in each channel using the Pillow library. There are total 3 channels in an image and therefore we will get a list of three values.Original ImageAlgorithmStep 1: Import Image and ImageStat libraries. Step 2: Open the image. Step 3: Pass the image to the stat function of the imagestat class. Step 4: Print the standard deviation of the pixels.Example Codefrom PIL import Image, ImageStat im = Image.open('image_test.jpg') stat = ImageStat.Stat(im) print(stat.stddev)Output[72.25694839223894, 66.24724750077299, 65.50769196475312]

In this program, we will blur an image using a rank filter. The ImageFilter class in the pillow library contains a function called RankFilter() which helps to apply the rank filter. It takes two parameters, size of the kernel and rank. Rank is 0 for a min filter, size*size/2 for a median filter and size*size-1 for a max filter.Original ImageAlgorithmStep 1: Import Image and ImageFilter from Pillow. Step 2: Open the image. Step 3: Call the rankfilter() method and specify the size and rank. Step 4: Display the output.Example Codefrom PIL import Image, ImageFilter im = Image.open('image_test.jpg') im1 = ... Read More

In this program, we will blur an image using a Box filter. The ImageFilter class in the pillow library contains a function called BoxBlur() which helps to apply the box blur filter. It takes only one parameter that is blur radius.Original ImageAlgorithmStep 1: Import Image and ImageFilter from Pillow. Step 2: Open the image. Step 3: Call the boxblur() method and specify the radius. Step 4: Display the output.Example Codefrom PIL import Image, ImageFilter im = Image.open('image_test.jpg') im1 = im.filter(ImageFilter.BoxBlur(radius = 7)) im1.show()Output

In this program, we will blur an image using a Gaussian filter. The ImageFilter class in the pillow library contains a function called GaussianBlur() which helps to apply the gaussian blur filter. It takes only one parameter that is blur radius.Original ImageAlgorithmStep 1: Import Image and ImageFilter from Pillow. Step 2: Open the image. Step 3: Call the gaussianblur() method and specify the radius Step 4: Display the output.Example Codefrom PIL import Image, ImageFilter im = Image.open('image_test.jpg') im1 = im.filter(ImageFilter.GaussianBlur(radius = 9)) im1.show()Output

In this program, we will apply a minimum filter on an image using the pillow library. In median filtering, the value of each pixel in a selected window of the image is replaced by the median of that window. The filter function is used to apply different filters using the pillow library.Original ImageAlgorithmStep 1: Import Image from Pillow. Step 2: Open the image. Step 3: Call the filter function and specify the median filter. Step 4: Display the output.Example Codefrom PIL import Image, ImageFilter im = Image.open('testimage.jpg') im1 = im.filter(ImageFilter.MedianFilter(size = 7)) im1.show()Output

In this program, we will apply a minimum filter on an image using the pillow library. In mode filtering, the value of each pixel in a selected window of the image is replaced by the mode of that window. The filter function is used to apply different filters using the pillow library.Original ImageAlgorithmStep 1: Import Image from Pillow. Step 2: Open the image. Step 3: Call the filter function and specify modefilter. Step 4: Display the output.Example Codefrom PIL import Image, ImageFilter im = Image.open('testimage.jpg') im1 = im.filter(ImageFilter.ModeFilter(size = 7)) im1.show()Output

In this program, we will apply a minimum filter on an image using the pillow library. In maximum filtering, the value of each pixel in a selected window of the image is replaced by the maximum pixel of that window. The filter function is used to apply different filters using the pillow library.Original ImageAlgorithmStep 1: Import Image from Pillow. Step 2: Open the image. Step 3: Call the filter function and specify maxfilter.
