1. A method for reducing a media data size while maintaining a target perceptual quality, the method comprising:
receiving an original media for processing to a target Psychovisual Compression Index (PVCI);
determining a plurality of Psychovisual Compression (PVC) metrics for the original media;
processing the original media using a trained neural network to identify psychologically important features of the original media using the plurality of Psychovisual Compression (PVC) metrics;
generating a resized media based on the plurality of Psychovisual Compression (PVC) metrics and the psychologically important features of the original media, the resized media comprising the psychologically important features of the original media and being a smaller data size compared with the original media;
determining a Psychovisual Compression Index (PVCI) value for the resized media;
comparing the PVCI value of the resized media to a threshold value of the target Psychovisual Compression Index (PVCI);
determining that the PVCI value of the resized media meets or exceeds the threshold value of the target Psychovisual Compression Index (PVCI);
sending the resized media to a website browser on a device of a user, the sending the resized media to the website browser of the user being faster than sending the original media to the website browser of the user based on the smaller data size of the resized media compared with the original media, the resized media comprising the psychologically important features of the original media;
receiving a previously processed media file having a PVCI value that meets or exceeds the threshold value of the target Psychovisual Compression Index (PVCI);
formatting the previously processed media file based on the website browser and a device type of the device of the user to create a reformatted previously processed media file;
resizing the reformatted previously processed media file based on the website browser and the device type to create a resized and reformatted previously processed media file; and
sending the resized and reformatted previously processed media file to the website browser on the device of the user, the sending the resized and reformatted previously processed media file using a global content delivery network (CDN), the using the global content delivery network (CDN) decreasing latency of the sending the resized and reformatted previously processed media file compared with the sending the resized media.
