The open mobile phone platform was published by Google and the Open Handset Alliance which is consisted of 33 mobile phone manufacturers and suppliers, the software and hardware suppliers and the Telemunication panies. The topic of my paper is to study the facial recognition technology, making use of the handled devices, which is based on the program platform of android.The main contents of this paper are as following: First, it uses intelligent mobile phone to get the image of human face. Then, it adjusts the face image to meet the need of the relative recognition algorithm. And last it pares the face image with the ones in the storeroom of the face image to get the result of the recognition.The major methods of this paper is as following: firstly, getting the face images from the Andrews phone, and making a pretreatment to the face images, such as wallpapers graying, histogram equalization, smoothing filter of the images and so on。 thirdly, making the face images which are to be identified project onto the eigenvectors and getting the face image which is the nearest to the eigenvectors with the method of the closest to finish the recognition phrase. Thus the person39。 JNI。 Image preprocessing。 PCA目 錄1 引言 ................................................................................................................................1 背景和意義 ............................................................................................................1 人臉識(shí)別技術(shù)研究現(xiàn)狀 ........................................................................................1 本課題研究意義 ....................................................................................................2 本文主要內(nèi)容及結(jié)構(gòu) ............................................................................................32 研究方案及技術(shù)路線 ...................................................................................................4 研究內(nèi)容 ................................................................................................................4 研究對(duì)象 ........................................................................................................4 制約識(shí)別率的關(guān)鍵問題 ................................................................................4 研究方案 ................................................................................................................4 相關(guān)人臉識(shí)別算法比較 ................................................................................4 運(yùn)用程序功能分析 ........................................................................................5 研究方案的確定 ............................................................................................6 技術(shù)路線 ................................................................................................................63 人臉圖像獲取 ................................................................................................................7 ANDROID 編程平臺(tái) ................................................................................................7 Android 開發(fā)平臺(tái)搭建 ..................................................................................7 Android 開發(fā)簡介 ..........................................................................................8 人臉圖像獲取 ........................................................................................................9 Android 應(yīng)用程序組件(Activity 簡介) .......................................................9 相關(guān)文件夾建立 ..........................................................................................11 控制照相機(jī)照相 ..........................................................................................114 圖像預(yù)處理 .................................................................................................................12 彩圖灰度化 ..........................................................................................................12 直方圖均衡化 .......................................................................................................13 圖像平滑濾波 ......................................................................................................14 邊沿檢測 ..............................................................................................................15 人臉部位提取 ..........................
