灰度值-
For the anticounterfeiting of printings ( such as certificate ), the existent many ways ( such as rainbow holograms ) are not available as the need for special use : anti - distortion and anti - copy. basing in the double - random - phase transform, this article puts forward a new way that two - dimensional bar code is used as anticounterfeiting label with anti - printing ? scanning and anti - damage properties. the major job are : ( 1 ). basing in the ascii codes, numerals and alphabets are encoded and subsequently transformed into two - value bar code matrix figure. later, using amplitude - based double - random - phase transform, the enciphered gray scale figure is formed. by computer simulation ( 4f system ) and printing as well as scanning ( 20 times ), we get the result that the gray scale figure with little miscoding rate ( 0. 0026 ) by “ matrix expanding way ”
本文主要開展了以下三項研究工作: （ 1 ） .用自定義編碼方案，將數字和字母（ ascii碼）轉換成二值條碼圖;對該圖形進行振幅型雙隨機相位加密變換，得到原信息的加密灰度圖;通過4f光學系統計算機模擬和列印-掃描實驗，證明本文提出的「矩陣擴展法」灰度圖具有較小的誤碼率，對於20次列印-掃描實驗，誤碼率不大於0 . 0026 。 -
It includes the following aspects : adopting the partial differential equations and neighborhood average smoothing methods to reduce image noises. mapping the rgb three - color and gray scale histogram to study - 3 - the relationship of flame features and temperature field distribution. the methods of calculate important parameters about the average gray value, the flame area and the flame shape center coordinate are given
採用圖象相加、偏微分、鄰域平均等方法來消除圖象噪聲；繪制圖象的r 、 g 、 b三色直方圖來研究火焰幅度特徵分佈與溫度分佈的關系；給出計算平均灰度、火焰面積大小、火焰形心坐標等重要參數的方法；用彩色等溫區或等溫線重構溫度場分佈。 -
