Wand wavelet_denoise() function in Python Last Updated : 09 Mar, 2023 Comments Improve Suggest changes Like Article Like Report This method is same as removing noise from image using soften() function. But this method removes noise by applying a wavelet transform which is more convenient and effective. The threshold argument should be a value between 0.0 & quantum_range, Syntax : wand.image.wavelet_denoise(threshold, softness) Parameters : ParameterInput TypeDescriptionthresholdnumbers.Realvalue between 0.0 & quantum_rangesoftnessnumbers.Realapply softness to image Source Image: Example 1: Python3 # Import Image from wand.image module from wand.image import Image # Read image using Image function with Image(filename ="koala.jpeg") as img: # denoise image using wavelet_denoise() function img.wavelet_denoise(threshold = 0.05 * img.quantum_range, softness = 0.0) img.save(filename ="vkoala.jpeg") Output: Example 2: Increasing threshold value Python3 # Import Image from wand.image module from wand.image import Image # Read image using Image function with Image(filename ="koala.jpeg") as img: # denoise image using wavelet_denoise() function img.wavelet_denoise(threshold = 0.065 * img.quantum_range, softness = 0.00) img.save(filename ="vkoala2.jpeg") Output: Comment More infoAdvertise with us R RahulSabharwal Follow Improve Article Tags : Python Python-wand Practice Tags : python Explore Python FundamentalsPython Introduction 3 min read Input and Output in Python 4 min read Python Variables 5 min read Python Operators 5 min read Python Keywords 2 min read Python Data Types 8 min read Conditional Statements in Python 3 min read Loops in Python - For, While and Nested Loops 7 min read Python Functions 8 min read Recursion in Python 6 min read Python Lambda Functions 5 min read Python Data StructuresPython String 5 min read Python Lists 5 min read Python Tuples 4 min read Dictionaries in Python 3 min read Python Sets 6 min read Python Arrays 7 min read List Comprehension in Python 4 min read Advanced PythonPython OOP Concepts 11 min read Python Exception Handling 6 min read File Handling in Python 4 min read Python Database Tutorial 4 min read Python MongoDB Tutorial 2 min read Python MySQL 9 min read Python Packages 12 min read Python Modules 7 min read Python DSA Libraries 15 min read List of Python GUI Library and Packages 11 min read Data Science with PythonNumPy Tutorial - Python Library 3 min read Pandas Tutorial 6 min read Matplotlib Tutorial 5 min read Python Seaborn Tutorial 15+ min read StatsModel Library- Tutorial 4 min read Learning Model Building in Scikit-learn 8 min read TensorFlow Tutorial 2 min read PyTorch Tutorial 7 min read Web Development with PythonFlask Tutorial 8 min read Django Tutorial | Learn Django Framework 10 min read Django ORM - Inserting, Updating & Deleting Data 4 min read Templating With Jinja2 in Flask 6 min read Django Templates 7 min read Python | Build a REST API using Flask 3 min read How to Create a basic API using Django Rest Framework ? 4 min read Python PracticePython Quiz 3 min read Python Coding Practice 1 min read Python Interview Questions and Answers 15+ min read Like
