Monitoring web site content

摘要

Systems and methods for monitoring Web page content associated with processing a resource request are provided. A client computing device generates a sample image corresponding to a set of resources rendered in response to a resource request. A processing component, such as an image analysis component, then compares the sample image with an averaged reference image to identify a compared image. The averaged reference image is determined from averaging a pixel intensity value for each pixel in a first reference image with a pixel intensity value for each pixel in a second reference image. These first and second reference images both correspond to the same set of requested resources. The processing component then weights the compared image to produce a weighted compared image and determines whether a sum of the intensity values for each pixel in the weighted compared image exceeds a threshold. Aspects of systems and methods for generating an alert message if the threshold is exceeded are also provided.

1. A computer-implemented method comprising:
generating a first reference image corresponding to a first rendering of at least a portion of a set of resources, wherein the first reference image comprises a pixel intensity value for individual pixels in the first reference image; generating a second reference image corresponding to a second rendering of the same at least a portion of the set of resources in the first rendering, wherein the second reference image comprises a pixel intensity value for individual pixels in the second reference image; determining an image weight map including a weight for individual pixels corresponding to the respective pixels in the first and second reference images, wherein individual weights are determined based on the difference of the corresponding pixel intensity value between the first and second reference images; generating a sample image corresponding to a third rendering of the same at least a portion of the set of resources in the first rendering, wherein the sample image comprises a pixel intensity value for individual pixels in the sample image; and causing transmission of an alert message indicating an inconsistency in the third rendering of the same at least a portion of the set of resources in the first rendering, wherein the inconsistency is determined based, at least in part, on the image weight map and wherein the alert message includes an identification of an affected pixel area, wherein the method is implemented by a computer system configured with specific executable instructions.
