Abstract: A method automatically separates out the defect image from a thermogram sequence based on the physical characteristics of the defect of a conductive material in electromagnetic field. Defect area radiates more heat than other area, when it is mapped to the histogram of the image to be separated, the defect area is located in the top-end of histogram, and the proportion of defect area is smaller to the background or other area. The method equally divides the histogram of the image to be separated into multi groups, and calculates the first derivative ki of total pixel number Si of group i, finds the maximum absolute value of ki, i.e. |ki|max, where i is expressed as imax; if imax is the last group, Wn is regarded as threshold T, otherwise, Wimax+1 is selected as threshold T. The pixels that less than threshold T are removed to obtain the defect image in ECPT.

Abstract: Many search engines attempt to understand and predict a user's search intent after the submission of search queries. Predicting search intent allows search engines to tailor search results to particular information needs of the user. Unfortunately, current techniques passively predict search intent after a query is submitted. Accordingly, one or more systems and/or techniques for actively predicting search intent from user browsing behavior data are disclosed herein. For example, search patterns of a user browsing a web page and shortly thereafter performing a query may be extracted from user browsing behavior. Queries within the search patterns may be ranked based upon a search trigger likelihood that content of the web page motivated the user to perform the query. In this way, query suggestions having a high search trigger likelihood and a diverse range of topics may be generated and/or presented to users of the web page.

Another approach includes receiving an indication of one or more incoming communication items addressed to a first user and an encrypted token associated with one or more identifiers characterizing the one or more communication items, decrypting the encrypted token to derive a decrypted token to enable verification of the token, and applying a predetermined rule based on the outcome of the verification to screen incoming communication items.
