    1 ) Describe with an example how run Run Length Encoding can be used to compress an image

    Burst length coding is a lossless data compression algorithm. Compresses data by reducing the amount of repetitive, sequential data called start. It does this by saving the number of runs and the data.

    Run Length Encoding is the Lossless compression algorithm that converts consecutive identical values into a code consisting of the character and the number marking the length of the run. Replace each row with numbers that say how many consecutive pixels are the same colour, always starting with the number of white pixels.

    Replace a sequence of repeated identical data in the file with a count and single data ex: aaabbcddddd After RLE compression *3a *2b c *5d

    Run length encoding (RLE), which is used to save space when storing digital photos, is based on this principle. We replace each row with values that indicate how many consecutive pixels are the same color, always starting with the number of white pixels, in run length encoding.

    Run Length Encoding is a form of lossless compression. It counts the text and number of consecutive occurrences of each character called run. There are two pairs, the first is count and the second is the character. RLE stores the same data using fewer bytes. By reducing the number of repetitive characters and numbers, the file size will be compressed. Example: aaaabbcccddd is (4, a) (2, b) (3, c) (3, d).

    Run Length Encoding is a type of lossless compression. It can compress an image by repeating the same color over and over again by just compressing the color that has the most amount of pixel in it. Example, the color of your shirt.

    Run length Encoding uses the same amount of space, it is a lossless compression it replace a sequence of number or characters.
