What we can do with these transformations, we use them to correct distortions or perspective issues from arising from the point of view an image was captured.There are two types of well-known transformation on…

Glare removal With Inpainting[OpenCV Python]
Glare is a visual sensation caused by excessive and uncontrolled brightness. It can be disabling or simply uncomfortable. It is subjective, and sensitivity to glare can vary widely. Older people are usually more sensitive to glare due to the ageing characteristics of the eye.First, We need to detect the place where the glare exists. We can easily identify them using global binarization since when a glare exists commonly, that pixel value is higher than 180. Using that, we ca…

Images are JUST NumPy Arrays
How computes can read the images, How our native python handles the images? Those questions were asked when I started to learn computer vision. I’ve started with python. There are a lot of libraries in python for image processing such as matplotlib, OpenCV, scipy.ndiamge and scikit-image. So whenever an image is read using any of these libraries then that image is actually read as NumPy ndrray. Whenever you are going to perform any operations on these images, essentially, yo…

An Analysis of Edge Detection Depth
Sorry to disappoint but no- I am not referencing WWE superstar Edge but rather the edges of an image used online. This is an important topic as — when programmers are trying to search or identify objects in an image — finding the border or edge of the image is very important. This article will look at the fundamentals of edges with the main focus on various methods for edge detection. What is an edge?Essentially an edge is a discontinuity representing changes in an image attr…

Developing an API is more relaxed than documenting an API. So how can we document an API? We have some tools that can generate the API documents for us automatically. We will see how we can document the Spring boot API with Swagger2.Swagger2 is a fantastic tool to document the REST API. API Properties can be described in JSON or YAML metadata in Swagger2. The Swagger UI is a beautiful thing to view our API. It will generate HTML documentation …
how to achieve data hiding in java
OOPS CONCEPTData hiding
The outside person can't access our internal data directly or our internal data should not go directly to the outside person .this oops feature is called data hiding, After validation or identification, we can access our internal data.
Example-: 1.After providing a proper username and password we can able to access our Gmail inbox
2.Even though we are valid customers of the bank. we can access our account information, but we can't access o…
