In an image, a boundary is an element that separates an object from the background of the image or two different regions within an image. Boundary provides information about the shape and structure of objects present in the image. Boundaries are mainly classified into the following two types: Inner Boundary It is the boundary of an object within an image that separates it from the image background. The inner boundary is basically the outline of the object and provides information about the shape of the object. Therefore, by extracting the inner boundary of an object, we can identify and analyze ... Read More

An optical or visual phenomenon that creates the perception of distortion, movement or any other type of fascinating visual effect by using back and white patterns is referred to as back and white optical illusion. These back and white patterns utilize the way our eyes and brain process the visual information and create an illusion to mislead our perception. The back and white optical illusions use various black and white patterns, shapes, and lines arranged in a specific style. These arrangements are made such that they can create illusion of movement, distortion, depth, and more. In this article, we will ... Read More

In MATLAB, for removing NaN value from a matrix, the following two functions are most widely used. remmissing () isnan () Now let us understand the removal of NaN value from a matrix in MATLAB using these two functions with the help of example programs. Removing NaN Values Using the isnan () Function In MATLAB, we can use the "isnan()" function to find the NaN values in a matrix and then can be used to remove them using logical indexing. The "isnan ()" function returns a value TRUE (logic 1) for NaN elements and FALSE (logic 0) for ... Read More

Introduction A popular statistical method for comprehending and simulating the connections between variables is regression analysis. The dependent variable is frequently assumed to have a normal distribution, though. The accuracy and dependability of the regression model may be jeopardized if this assumption is broken. The Box−Cox transformation offers a potent method for changing skewed or non−normal dependent variables to resemble a normal distribution in order to overcome this issue. We shall examine the Box−Cox transformation theory and use it in regression models in this post. We'll look at the transformation's justification and how it helps to satisfy the ... Read More

Introduction Multicollinearity, a phenomenon characterized by high correlation or linear dependence between predictor variables, poses significant challenges in regression analysis. This article explores the detrimental effects of multicollinearity on statistical models, focusing on issues such as unreliable coefficient estimates, reduced model interpretability, increased standard errors, and inefficient use of variables. We delve into the consequences of multicollinearity and discuss potential solutions to mitigate its impact. By understanding and addressing multicollinearity, researchers, and practitioners can improve the accuracy, reliability, and interpretability of regression models, enabling more robust analysis and informed decision−making. Problems with Multi−Collinearity Unreliable coefficient estimates Because ... Read More

Introduction Categorical variables are extensively utilized in data analysis and machine learning. Many algorithms are incapable of directly processing these variables, and they must be encoded or translated into numerical data before they can be used. Hot encoding and label encoding are two popular methods for encoding categorical data. One hot encoding provides a binary vector for each category in a categorical variable, indicating whether that category exists or not. We will discuss the ideas of one hot encoding and label encoding, as well as their advantages and disadvantages, and present examples of when and how to ... Read More
