Understanding Image Compression

What does RLE stand for in image compression?

• Run-Length Estimation

• Run-Length Encoding

• Run-Length Encoding Algorithm

• Random Length Encoding

What is a bitmap?

• A bitmap is a type of vector graphic.

• A bitmap is a grid of pixels representing an image.

• A bitmap is a file format for audio files.

• A bitmap is a method for compressing video.

How is a red pixel represented in binary for the heart icon?

• 11111111 11111111 00000000

• 00000000 11111111 00000000

• 11111111 00000000 00000000

• 00000000 00000000 11111111

Why do computers use compression algorithms for images?

• To enhance image colors and brightness.

• Computers use compression algorithms for images to reduce file size and improve efficiency in storage and transmission.

• To increase the resolution of images.

• To convert images into text format.

What does mapping pixels to bits mean?

• It involves changing the color depth of an image.

• It is a method for resizing images without losing quality.

• It means converting image pixel data into a binary format for digital storage and processing.

• It refers to the process of enhancing image quality.

What is the main advantage of using run-length encoding?

• It only works for numerical data types.

• It requires more processing power to decode the data.

• It increases the size of data by adding more elements.

• It reduces the size of data by compressing sequences of repeated elements.

Can you name one other image compression algorithm besides RLE?

• JPEG

• BMP

• PNG

• GIF
