Sketch to Stylized-Image: A Two-Stage Approach for Artistic Image Generation

Transforming sketches into artistic images is an essential task, especially for individuals without artistic expertise. Recent style transfer models struggle with applying styles to sketch images due to the absence of color information in the input image. To address this limitation, we propose a novel approach that leverages existing pre-trained models. Our method first colors the sketches using a well-performing pre-trained condition-based image generation model, and then applies style transfer to achieve the desired artistic effect. Experimental results demonstrate that our method effectively generates stylized sketch images with high quality, without the overhead of additional training.
