Abstract

Image mapping and processing methods, apparatuses and machine-readable media are disclosed. The methods include obtaining a panoramic video image, and demarcating the panoramic video image into a primary area and at least one ancillary area; determining a primary quantization parameter corresponding to the primary area, and an ancillary quantization parameter corresponding to the ancillary area, wherein the primary quantization parameter is smaller than the ancillary quantization parameter, with the quantization parameter being inversely proportional to an image quality; and encoding the primary area based on the primary quantization parameter, encoding the ancillary area based on the ancillary quantization parameter, and determining a coded panoramic video image.
