WebOct 1, 2024 · Build the Average RGB Database. The first step to create the mosaic image generator is by building a database which contains the average RGB value for each of the source images. So, for each of the source image, we calculate the average value for each of the RGB layer and then store it in a database, or in this case, a CSV file. WebUsing SIFT features, one popular way is to create a Bag of Visual Words framework where you take all of the features detected from all of the faces and you create a dictionary, usually with k-Means. Once you find these clusters, for each face you figure out which feature maps to which cluster then build a histogram.
