Doppler Shift — Embedded System A system that incorporates a computer, typically a microcontroller or microprocessor, as an intrinsic component is referred to as an embedded system. The engine control system of a modern car or the controller that controls a microwave oven are two examples of items with undetectable embedded systems. Real Time System A real-time system…

Photogrammetry-1 — I had previously written about Image Histogram here: Image Histogram Photogrammetry-1thanifbutt.medium.com A cumulative histogram sums the number of pixels having the current value or smaller than the current value. The following function computes the cumulative histogram def cumulativeHistogram(hist): """The function takes as input a histogram [np.array] and returns the cumulative histogram [np.array]""" cum_hist = np.zeros((256,1)) for i in range(256): cum_hist[i] = sum(hist[:i+1]) return cum_hist

Photogrammetry-1 — I am taking the Photogrammetry-1 course by Prof. Cyrill Stachniss which is available here: I have recently worked on Image Histogram as an assignment. Today, I will be talking about the same. A histogram is basically a graph with intensity values on x-axis while the number of pixels having…

DBC files — I have written an article on CAN bus here: CAN Bus Controller Area Network Busthanifbutt.medium.com Today, I want to talk about DBC files. The CAN signals are recorded using different data loggers like M-Logger. The signals are stored in different formats like a blf file. In order to read a blf file, we need a dbc…

Controller Area Network Bus — So, nowadays, I am working on CAN (Controller Area Network) Bus data. What is CAN Bus In most vehicles, different Electronic Control Units (ECUs) are responsible for various operations such as an ECU for brake pedal pressure. These ECUs communicate with each other through the CAN Bus. Why it is important It’s important because we can model vehicle…

Jupyter Notebook — I had to choose a topic for my presentation so I chose Julia. Starting off by installing it. Here are the steps to add Julia to Jupyter Notebook: Download Julia through this. Open the Julia command line and write: using Pkg Press Enter Then type: Pkg.add(“IJulia”) Press Enter Wait for the installation to complete. Create a new notebook in Jupyter. Select Julia as the kernel. Write this command in a cell: println(“Hello World”) Run the cell.

My first lecture during PhD — So, I have just given my lecture as part of a module of a compulsory course which I am taking. The task was to design and deliver a lecture on a topic of our choice using active learning which means to engage the audience in some form of activity instead…

Introductory Course for PhD Students — So, I started my PhD in January. I came to Sweden on 1st February. While I was applying for the position, I thought that as Sweden is in Europe so there will only be research work without any course work but after coming here I got to know that I…

C++ — Libraries are collection of symbols or collection of function implementations. Basically multiple object files that are logically connected. There are 2 types: Static and Dynamic. Static end with .a while dynamic end with .so Header file for declaration of a function as .hpp file .cpp file the main program including .hpp…
