OpenCV 11: Masking
Select an image to mask on, and create a blank image to create the shape of the mask. Create a circle and rectangle mask respectively. Use bit operation to combine the mask and the image.
BeBOP Chapter 13 Key Note: Analogue to Digital / Digital to Analogue
Analogue-To-Digital A transducer is a device that converts the input energy of one form into the output energy of another. An appropriate transducer that converts the detected analogue quantity to a suitable form is called a sensor. The output from the sensor may undergo some form of signal processing like filtering and amplification before being […]
Building XNOR Gate
XNOR and XOR gates are primitive logic gates. In XNOR, when two inputs are the same, the output is logic 1 and when the two inputs are different, the output is 0. This gate can be built using pass-logic transistors meaning that one of the inputs is connected to the source of the transistors rather […]
OpenCV 10: Bitwise Operation
First create a blank image using numpy to work on, and draw a circle and a rectangle on separate blank images. Bitwise AND Bitwise OR Bitwise XOR Bitwise NOT
BeBOP Chapter 12 Key Note: State Machine
State Diagrams State diagrams are used to abstract functions such as a controller, it consist of a set of states through which it sequences. The current state depends on the previous state combined with the previous values and the next state depends on the current state combined with the current values. The arcs connecting the […]

BeBOP Chapter 11 Key Note: Complex Function
Scalar and Vector Notation A single signal carrying one bit of binary data is known as a scalar entity. A set of signals carrying similar data can be gathered together into a group known as a vector. A key advantage of vector notation is that it allows all of the signals comprising the vector to […]

BeBOP Chapter 10 Key Note: Karnaugh Maps
Maurise Karnaugh & Karnaugh Maps In 1953, American physicist Maurise Karnaugh invented a form of logic diagram called a karnaugh map. The karnaugh map comprises a box for every line in the truth table. The binary values above the boxes are those associated with the inputs. Unlike a truth table, in which the input values […]
