針對Mean Shift算法不能跟蹤快速目標、跟蹤過程中窗寬的大小保持不變的特點。首先，卡爾曼濾波器初步預測目標在本幀的可能位置；其次， Mean Shift算法在這點的鄰域內尋找目標真實的位置；最后，在目標出現大比例遮擋情況時，利用卡爾曼殘差來關閉和打開卡爾曼濾波器。實驗表明該算法在目標尺度變化、遮擋等情況下對快速運動的目標能夠取得較好的跟蹤效果。
將現行的供暖計費方式由按建筑面積計費變為按消耗的熱能計費是供暖計費方式發展趨勢，為了滿足這一計費方式變化的需要，設計了基于IC卡的預付費式新型供暖計費系統，通過測量用戶采暖系統進出口的溫度和流量，計算用戶消耗的熱能，利用IC卡記錄用戶預付費的金額和當年熱能的單價，根據熱能消耗和當年熱能的單價計算用戶采暖費，根據實際發生的供暖費用和預付費金額控制供暖的開停，這一計費方式的變化使供暖計費更趨合理。
Abstract:
It is trend that the mode of heat charging is changed from billing by building area to by thermal energy. In order to meet the needs of heat charging mode changing， a new system of heat charging based on IC card is proposed. The user?蒺s energy consumption is calculated by measuring the user inlet and outlet temperature and flow，using the IC card to record the prepaid amount and the current price of heat. The user?蒺s heating costs is calculated according to energy consumption and current price， according to actual heating costs and prepaid amount，the system controls the heating opening or stopping. It is more reasonable that calculated heating costs by user heat consumption
