Linear features, on the other hand, rendering rich geometric as well as radiometric information of the scene, would offer great advantage for automatic detection and matching tasks. Linear features, without the need to specify their forms, are basically the sets of a series of line features. The simpler way of treating linear features can first of all begin with line features. This proposal is estimated to span two years. The major investigation scheduled for the first year is to explore the line features on the tasks of detection, matching, offering controls, registration and fusion. And the work in the second year would extend from line features to linear features, as well as from frame cameras to linear array cameras for the similar treatments as those included in the first year.線型特徵直線特徵偵測匹配套合融合Linear FeaturesLine FeaturesDetectionMatchingRegistrationFusion
