Even though our features are somewhat more expensive to compute than SURF due to the construction of the nonlinear scale space , but comparable to SIFT , our results reveal a step forward in performance both in detection and description against previous state-of-the-art methods .
 compare: features, SURF; compare: features, SIFT; compare: results, state-of-the-art methods; evaluate for: detection, results; conjunction: detection, description; evaluate for: detection, state-of-the-art methods; evaluate for: description, results; evaluate for: description, state-of-the-art methods
Given a phrase that describes the relationship between two words, extract the words and the lexical relationship between them. The output format should be "relation1: word1, word2; relation2: word3, word4". 
Option: conjunction, feature of, hyponym of, used for, part of, compare, evaluate for
