Lossless compression techniques include ____ (RLE), which replaces consecutive repeating pixels with shorter codes, ____, which assigns shorter codes to more frequent pixels, and ____ (LZW) compression, which builds a dictionary of patterns to replace repeated occurrences. These methods allow for image files to be compressed without any loss of ____ or ____, making them suitable for applications requiring precise image editing.
