Learning apparatus, estimation apparatus, learning method, estimation method, and computer programs

A learning device, comprising:

• a processor;
• and
• a storage medium having computer program instructions stored thereon, where executed by the processor, perform to:
• obtain a first image group including a plurality of successive time-series images including a reference image and generates first time-series information based on a difference between the reference image and each of the images in the first image group other than the reference image;
• and
• performs machine learning using the reference image and the first time-series information, thereby obtaining a first learning result that is to be used for estimating depth information on a target image, which is an image to be processed, and silhouette information on a subject captured in the target image based on the target image and second time-series information generated from a second image group including a plurality of successive time-series images including the target image.
