Could you build this?
Yes It is a compact image placeholder hashing algorithm and client library comparable to BlurHash. A competent prompt engineer can easily have an LLM implement image downsampling, DCT or color-splat encoding, and string serialization in standard languages.
Discussion
19 comments analyzed.
Competitors mentioned: BlurHash, ThumbHash, tiny JPEG placeholders, Potato WebP
Concerns raised: Visual artifacts: splats look weird and unnatural compared to alternatives, Weak at preserving global image features, especially for synthetic images, Excessive contrast in splat rendering implies features that don't exist, Local feature reproduction at expense of global feature loss
Feature requests: Tunable splat radius and opacity curves for softer rendering, Preserve global features alongside local features, Use padding bits to store additional feature data
