Before embarking on the valiant quest of coding images with secret messages, we first have to understand the nature of how images are represented in computers. And it all starts with "pixels". Pixels can be tho
In color images, pixels are often represented in the RGB color model. RGB stands for Red Green Blue. Each pixel is a mix of those three colors. RGB is great at modeling all the colors humans perceive by combining various amounts of red, green, and blue. Since a computer only understand...
We have an image of a girl. Look closely and you will notice that it is made up of small square boxes.These are called pixels. There are some limitations, as we see the images in their visual form, we as humans can easily differentiate the edges and colors. Unlike us, machines can...
These images are then analyzed by the computer one pixel at a time. Pre-processing Computers process, augment, and prepare image data before an algorithm is applied. Pre-processing ensures that image data satisfies the requirements of the model. Some common pre-processing steps include noise ...
Our server will respond by sending the requested file in a series of packets. Packets are parts of a file that range between 1,000 and 1,500 bytes. Packets have headers and footers that tell computers what's in the packet and how the information fits with other packets to create an ...

Simple logos are easier to understand and absorb, but more importantly, they’re easier to recall and remember! A simple logo will make it easier to catch the attention of someone walking by or make your product identifiable on crowded store shelves. ...
In coding, the decimal system works as it does in everyday life. Values are represented as base-10 numbers. However, computers work with binary (base 2), so these decimal numbers are often converted into binary for processing. Some programming languages also support hexadecimal (base-16) and...
In the image above, each function is represented by the yellow hexagons, and the partial derivatives are represented by the gray arrows on the left. Applying the chain rule, the value of derror_dweights will be the following: Python derror_dweights = ( derror_dprediction * dprediction_...
Mascot logosare represented by the face of a character or real person you use as an ambassador for your brand. They can humanize your business by creating a relatable personality. This works best for kids’ brands or those looking for a retro feel (e.g., Wendy’s, Colonel Sanders for KF...
