US 12,223,627 B2 · Oversmoothing progressive images

Abstract

A technique for improving progressive encoded JPEG includes displaying an oversmoothed version of an image as the image data is being received. The oversmoothed image may be smoothed according to a smoothing kernel, e.g., a convolution kernel (such as a Gaussian). The oversmoothed image is a first layer over which other image layers are displayed. It is noted that the oversmoothed image may present a recognizable version of the image to a user, including recognizable versions of various image features (e.g., persons, objects). As the other layers are rendered on the display, these image features remain visible to the user. That is, the image features are not artifacts that may disappear with the rendering of final image layers; this may occur with the conventional progressive encoded images and interferes with the user experience.

Dependent claims

A method, comprising:

transmitting, from a client, a request to access image data representing an image;
after transmitting the request, receiving a first portion of the image data, the first portion of the image data representing a first layer including a set of features;
in response to determining that a download time for receiving the image data satisfies a condition:
rendering, as the first layer, a smoothed version of the image on a display associated with the client, the smoothed version of the image including more than one color;
and
while rendering the smoothed version of the image on the display associated with the client, receiving a second portion of the image data, the second portion of the image data representing a second layer;
and
rendering the second layer on the display while displaying the set of features of the first layer on the display.
