Max-mean and max-median filters

Web31 aug. 2024 · The goal is to take the average of the pixels staying in kernel and take this mean value as the output pixel. Therefore, we can create any mean kernel by using the following formula: “Image by Author”. Basically for a 3x3 mean filter we have this one: “Image by Author”. Or for a 5x5 mean filter: “Image by Author”. Webthis formula is to find out the users who match with conditions (do transaction at least 2 before end_date parameter, and atleast doing 1 transaction in between start_date parameter and end_date parameter) after that i add to context this filters to find out the users first. and i made filters date_range with this calculate
