Characters that were already humanoid being depicted as human. This can include dolls, androids, furries, humanoid robots or mecha, and monster humanoids, with any non-human traits like doll joints, obvious mechanical features, fur, horns, wings, impossible skin colors, etc removed. Since impossible hair and eye colors are already commonplace in anime depictions of regular humans, those features do not need to be removed to qualify as humanization.
For characters that were not already humanoid, such as animals and non-humanoid robots, use personification instead.
