They replace the value of an image pixel with a combination of its neighbors. Basic operations in images. Shift Invariant. Linear. Thanks to David Jacobs for the use of some slides. Consider 1D images. Summary of the measure of the characteristics of individuals in groups.. A descriptive statistic talks about a single characteristics within a given group. Lots of descriptive statistics are summarizing lots of characteristics but all within a given group.. Correlation. A statistical way to measure the relationship between two sets of data.. Means that both things are observed at the same time.. Causation. Means that one thing will cause the other.. You can have correlation without causation.
