Benchmark Datasets with Ground Truths for Clustering
It is very common among researchers or graduate students who are working on clustering papers to consider only a small number of datasets, which obviously is too few to make any evaluations rigorous enough. The other reason is that most of datasets are boring and there is really anything of significant in them. Other type

Futuristic Projects Ideas
One can work on any of the following projects. Many of these ideas have already been implemented in real world scenario but one could find the different way to implement much more smartly. Smart traffic signals to optimize traffic flow to reduce congestion This project aims at building a system for equitable distribution of traffic

Image Pyramid – Expanding Image
Image pyramid is widely used in computer vision which allow us to convert an image / frame to a different size ( smaller or larger ) than its original size. There are two possible method available in openCV which allow us to up size and down size an image. A collection of images, all of

ECG or heartbeat datasets
I have gone through all possible open source ECG datastes available for classification problem. The idea of this blog post is to share this useful information with research community. It includes the details about the open source ECG datasets i have found and are useful to train a model. You guys can also share some

How to use HRV Explorer camera measurement accurately??
HRV Explorer heart rate variability measurements can tell you a lot about changes happening in your body. You need to pay great attention when using a camera based heart rate monitor as these gadgets are highly sensitive and camera measurement highly depends on your behavior during the reading (reading time around 2 minutes). If you

Heart Rate Variability (HRV) and personalize care using smartphone camera
The cardiovascular diseases are major cause of mortality across the globe contributing 31% of global death burden [1]. The electrocardiography (ECG) is used to detect abnormalities in the cardiac rhythms during the onset of cardiovascular problems [2], mostly diagnosed when damage has been already done. It is evident that rhythms of heart started to change

Motion Detection using Frame Differencing and Mean Background Model
Instead of using static background model to find difference in current frame, I am using frame difference technique where current frame is compared or subtracted from previous frame. The difference depends upon speed of moving objects. Making a fair analysis is very difficult. Find the code bellow to find difference in frames. VideoCapture capture("ewap/seq_hotel.avi"); Mat
