Aspect ratio conversion for automated image generation

A system comprising a memory storing instructions and one or more processors configured by the instructions to perform operations comprising:

• receiving, from a user device, an image generation request comprising a prompt;
• responsive to receiving the image generation request, generating, by a processor-implemented automated image generator and based on the prompt, a first image having a first aspect ratio;
• determining two or more candidate regions of interest in the first image;
• encoding, by a text encoder, the prompt to obtain an embedding of the prompt;
• encoding, by an image encoder, each of the two or more candidate regions of interest to obtain an embedding of the candidate region of interest;
• comparing the embedding of each of the two or more candidate regions of interest with the embedding of the prompt to obtain a prompt alignment indicator for each of the two or more candidate regions of interest in the first image, the prompt alignment indicator indicating a level of alignment between each candidate region of interest and the prompt;
• determining a target region of interest among the two or more candidate regions of interest in the first image, the target region of interest being determined automatically based on a comparison among two or more prompt alignment indicators for the two or more candidate regions of interest;
• cropping the first image at the target region of interest to obtain a second image, the second image having a second aspect ratio that is different from the first aspect ratio;
• and
• causing presentation of the second image on the user device.

A non-transitory computer-readable storage medium, the computer-readable storage medium including instructions that when executed by at least one computer, cause the at least one computer to perform operations comprising:

• receiving, from a user device, an image generation request comprising a prompt;
• responsive to receiving the image generation request, generating, by a processor-implemented automated image generator and based on the prompt, a first image having a first aspect ratio;
• determining two or more candidate regions of interest in the first image;
• encoding, by a text encoder, the prompt to obtain an embedding of the prompt;
• encoding, by an image encoder, each of the two or more candidate regions of interest to obtain an embedding of the candidate region of interest;
• comparing the embedding of each of the two or more candidate regions of interest with the embedding of the prompt to obtain a prompt alignment indicator for each of the two or more candidate regions of interest in the first image, the prompt alignment indicator indicating a level of alignment between each candidate region of interest and the prompt;
• determining a target region of interest among the two or more candidate regions of interest in the first image, the target region of interest being determined automatically based on a comparison among two or more prompt alignment indicators for the two or more candidate regions of interest;
• cropping the first image at the target region of interest to obtain a second image, the second image having a second aspect ratio that is different from the first aspect ratio;
• and
• causing presentation of the second image on the user device.
