2009_Image_Compression_Algorithm_of_SPIHT_Based_on
- 一種基于塊樹結構的SPIHT數字圖像壓縮算法: 在分析圖像經過小波變換后所具有的特性的基礎上,提出了一種改進的SPIHT算法.由于低頻系數占據圖像的百分之九十以上的能量,在圖像的重構中十分重要,所以,對這些系數不進行壓縮而直接傳輸 而最高頻系數相對不重要,所以不做處理,只在圖像重構時以指定的數值予以重構,因此不僅提高了圖像的質量,同時提高了圖像的壓縮率.在具體的算法中,提出了塊樹的結構,減少了算法所需的內存,拓寬了算法的應用范圍.-A tree structure based on the SP

- 本设计的指导思想是利用红外发光管发射红外线，红外接收管接收此红外线，并将其放大、整流形成高电平信号.当有人或物挡住红外光时，接收管没有接收到红外信号，放大器将输出低电平，同时将这个电平信号送入单片机进行控制计数，并经译码驱动电路使数码管显示数值。这样就得到要统计的人或物的数量。-The design of the guiding idea is to use infrared emission infrared LED and infrared receiver to receive the i
