分類定義
分類是根據對象、要素或區域在圖像上的外觀將其分配圖像語義類別。 通常在三個層次的置信度和精確度之間進行區分。 檢測(Detection)是判斷特徵是否存在。 識別(Recognition)意味着關於特徵或對象的更高級別的知識,以便可以為對象分配一般類別或子類。 最後,辨識(Identification)意味着可以以足夠的信心和細節來指定對象或類別,以將其置於非常特定的類別中。 通常,解譯員可以通過將識別指定為“可能的”或“可能的”來限定他或她對解釋確認度。
Classification is the assignment of objects, features, or areas to classes based on their appearance on the imagery. Often a distinction is made between three levels of confidence and precision. Detection is the determination of the presence or absence of a feature. Recognition implies a higher level of knowledge about a feature or object, such that the object can be assigned an identity in a general class or category. Finally, identification means that the identity of an object or feature can be specified with enough confidence and detail to place it in a very specific class. Often an interpreter may qualify his or her confidence in an interpretation by specifying the identification as “possible” or “probable.”
