1Productivity
If conventional image processing systems are used for vector image generation, then image generation can be performed, but the process is time-consuming and computationally expensive
Solution Approach 1:
The system generates a mask image based on the outline before the main image generation process. This preliminary mask creation step guides the subsequent image generation model to focus computational resources only on the outlined region, avoiding unnecessary computations across the entire image area and thereby reducing overall computational cost and time.
Solution Approach 2:
The mask image serves as a spatial guide that localizes the image generation process to specific regions of interest defined by the outline. By confining the generative model's attention to only the outlined areas rather than processing the entire image canvas, the system achieves faster and more efficient computation while maintaining quality where needed.
2Shape
If conventional systems generate images, then raster images are produced, but vectorized images with scalable quality cannot be generated
Solution Approach 1:
The system uses the mask image as a template or copy that replicates the outline structure. This mask serves as a guide that the image generation model follows to create vector-like content within the outlined regions, enabling the production of scalable vectorized images rather than traditional raster images.
3Adaptability or versatility
If conventional image processing is used, then basic image generation is possible, but additional specific training is required for spatial context inputs
Solution Approach 1:
The mask component serves multiple functions: it processes the outline input, creates the guidance mask, and prepares it for the image generation model. This universal mask processing approach handles various spatial context inputs without requiring separate specialized training for each type of spatial input, thereby reducing overall training complexity while maintaining versatility.

AI summary
A method, apparatus, non-transitory computer readable medium, and system for image processing include obtaining an outline image and an input prompt, where the outline image includes an outline of a region and the input prompt indicates content for the region, generating a mask based on the outline image, where the mask indicates the region within the outline, generating a preliminary image based on the mask, where the preliminary image includes noise in the region indicated by the outline, and generating a synthetic image based on the input prompt, the mask, and the preliminary image, where the synthetic image depicts the content in the region indicated by the outline. A vectorized image is generated based on the synthetic image
