One Family Photo, Four Characters, One Coloring Book: A Cartoon-Style Run

We ran one family-of-four photo through LineArt in Cartoon style. Five pages, five scenes, four faces consistent throughout — the unedited result.

Our first case study followed one golden retriever puppy through a Realistic-style book. This time we raised the difficulty: a family of four — two parents, two kids — in Cartoon style. Keeping one dog recognizable across five pages is hard; keeping four people recognizable, each with their own face and hair, is the real test of a photo-to-coloring-book pipeline.

As before: one photo in, one book out, nothing retouched.

The input: a single family photo

We started with this family photo (a free-license photo from Pexels — the same kind of shot that's sitting in your camera roll after any weekend outing):

The source photo — a family of four in the park

Dad with one daughter on his shoulders, mom with the other by her side. Four faces, four hairstyles, one photo. That's the whole input.

Six minutes later: five pages, four consistent characters

We picked the Cartoon style — the cute chibi look made for kids — and five family scenes: park, beach, picnic, playground, and baking. Here are all five pages, exactly as the pipeline produced them:

Page 1 — piggyback in the park, just like the photo

Page 2 — beach day with a beach ball

Page 3 — picnic with sandwiches and lemonade

Page 4 — everyone on the playground slide

Page 5 — baking cookies in chef hats

Look at what carries through every page: dad's spiky hair, mom's long wavy hair and earrings, the older daughter's big curly hair, the younger one's polka-dot dress. Even the shoulder-ride from the source photo shows up on the pages. Five separate drawings that read as one book about this family — that's the consistency we sell.
