算法概覽

為了給用戶提供更好的算法實現成像效果，現在的集成手機都會接入一些第三方的圖像處理算法。MTK平臺的指南HAL3也在P2這一層提供接入的plugin。按圖像處理算法需要的算法實現幀數和攝像頭數量，大體可以分為三類：

單幀算法：

常見的集成單幀算法有：美顏算法(瘦臉、磨皮、指南大眼)、算法實現廣角鏡頭畸變校正算法、集成附加表情算法、指南單攝背景虛化算法(偽雙攝算法)等等，算法實現僅需單幀圖像輸入的集成算法都屬于單幀算法。一般情況下，指南輸入一幀圖像，算法實現算法處理完輸出一幀處理后的集成圖像。

多幀算法：

常見的指南多幀算法有：MFNR（多幀降噪）、HDR（高動態范圍）等等，需要連續多幀圖像輸入的算法都屬于多幀算法。一般情況下，輸入連續多幀圖像，算法處理完輸出一幀處理后的圖像。

雙攝算法：

最常見的雙攝算法是雙攝景深算法或者叫雙攝背景虛化算法，除此之外，也有彩色+黑白用于增強夜拍效果的雙攝算法。單幀算法和多幀算法僅需要獲取一個攝像頭的圖像。而雙攝算法需要獲取主、輔兩個攝像頭的圖像，并且一般還會要求主、輔攝像頭同步。分別獲取主、輔攝像頭的兩幀同步圖像，處理后輸出一幀主攝圖像，用戶也僅能看到主攝圖像。

根據這個大體上的分類，MTK HAL算法集成系列文章共三篇：

MTK HAL算法集成之單幀算法

MTK HAL算法集成之多幀算法

MTK HAL算法集成之雙攝算法

本文是其中的第一篇。這個系列文章均基于Android9.0，MT6763平臺，HAL版本是HAL3。

一、算法集成前的準備

在開展集成工作之前，首先要對算法有一個基本的評估，并且對于集成也應有一定的要求。

1. 1 算法要求及評估

處理效果好，不能比競品差，超過競品更佳。（這條和camera調試的主觀效果一樣，主觀性較強，往往一廂情愿，具體看項目要求吧）

各個場景及壓力測試下效果穩定。

處理后照片無色差、銳度和飽和度無損失，或者損失在可接受范圍。

達到可接受的分辨率，最好可達到攝像頭的最大分辨率。

處理時間越快越好，不超過競品時間、不超過項目和產品的目標時間。

無內存泄露，占用內存少。

提供必要的集成說明文檔，包括算法類型、輸入及輸出圖像要求、輸入參數要求等等。

注意：如果有條件，處理時間、內存占用、分辨率等等可量化的指標可要求算法提供方給出具體的參考數據，以便集成完后測試驗證。

1.2 算法集成要求

編譯時可根據項目控制是否集成算法。

運行時可以用參數控制是否啟用算法。

集成算法庫正常運行、壓力測試下效果穩定、無內存泄露。

1.3 算法集成的步驟

(1).根據算法選擇feature類型，如果與MTK提供的feature不能對號入座，則需要添加自定義feature。

(2).將算法對應的feature類型添加到scenario配置表。

(3).根據算法選擇plugin類型，編寫CPP文件實現plugin，掛載算法。

(4).如果算法不能復用Android和MTK提供的metadata，則還需要為算法配置自定義的metadata以便APP控制是否啟用算法。

首先，我準備了一個libwatermark.so，它僅僅實現了一個添加水印的功能，用它來模擬第三方的單幀算法庫。如果想了解添加水印的實現代碼，可以參考我另外一篇文章：Android 實現圖片加水印或logo。接下來，我們就按照集成步驟，逐步詳細講解。

二、 為算法選擇feature

2.1 MTK提供的feature

MTK在mtk_feature_type.h和customer_feature_type.h已經提供了一些feature。
vendor/mediatek/proprietary/hardware/mtkcam3/include/mtkcam3/3rdparty/mtk/mtk_feature_type.h：

NO_FEATURE_NORMAL       = 0ULL,    // MTK (bit 0-31)    MTK_FEATURE_MFNR        = 1ULL << 0,    MTK_FEATURE_HDR         = 1ULL << 1,    MTK_FEATURE_REMOSAIC    = 1ULL << 2,    MTK_FEATURE_ABF         = 1ULL << 3,    MTK_FEATURE_NR          = 1ULL << 4,    MTK_FEATURE_FB          = 1ULL << 5,    MTK_FEATURE_CZ          = 1ULL << 6,    MTK_FEATURE_DRE         = 1ULL << 7,    MTK_FEATURE_DEPTH       = 1ULL << 8,    MTK_FEATURE_BOKEH       = 1ULL << 9,    MTK_FEATURE_VSDOF       = (MTK_FEATURE_DEPTH|MTK_FEATURE_BOKEH),    MTK_FEATURE_FSC         = 1ULL << 10,    MTK_FEATURE_3DNR        = 1ULL << 11,    MTK_FEATURE_EIS         = 1ULL << 12,    MTK_FEATURE_AINR        = 1ULL << 13,    MTK_FEATURE_DUAL_YUV    = 1ULL << 14,    MTK_FEATURE_DUAL_HWDEPTH  = 1ULL << 15,    MTK_FEATURE_AIS         = 1ULL << 16,    MTK_FEATURE_HFG         = 1ULL << 17,    MTK_FEATURE_DCE         = 1ULL << 18,

vendor/mediatek/proprietary/hardware/mtkcam3/include/mtkcam3/3rdparty/customer/customer_feature_type.h：

// ThirdParty (bit 32-63)    TP_FEATURE_HDR          = 1ULL << 32,    TP_FEATURE_MFNR         = 1ULL << 33,    TP_FEATURE_EIS          = 1ULL << 34,    TP_FEATURE_FB           = 1ULL << 35,    TP_FEATURE_FILTER       = 1ULL << 36,    TP_FEATURE_DEPTH        = 1ULL << 37,    TP_FEATURE_BOKEH        = 1ULL << 38,    TP_FEATURE_VSDOF        = (TP_FEATURE_DEPTH|TP_FEATURE_BOKEH),    TP_FEATURE_FUSION       = 1ULL << 39,    TP_FEATURE_HDR_DC       = 1ULL << 40,   // used by DualCam    TP_FEATURE_DUAL_YUV     = 1ULL << 41,    TP_FEATURE_DUAL_HWDEPTH = 1ULL << 42,    TP_FEATURE_PUREBOKEH    = 1ULL << 43,    TP_FEATURE_RAW_HDR      = 1ULL << 44,    TP_FEATURE_RELIGHTING   = 1ULL << 45,

MTK提供的這些feature可以滿足絕大多數算法的集成，在可以對號入座的情況下，我們直接使用已有feature即可。如果不能夠滿足我們的要求，可以參考下節內容添加新的feature。

2.2 添加自定義feature

本來單幀算法對應的feature可以選擇MTK提供的MTK_FEATURE_FB和TP_FEATURE_FB，但是為了講解如何添加新feature，我們選擇添加一個自定義feature：TP_FEATURE_WATERMARK。

三、 將算法對應的feature添加到scenario配置表

在我們打開camera進行預覽和拍照的時候，MTK HAL3會執行vendor/mediatek/proprietary/hardware/mtkcam3/pipeline/policy/FeatureSettingPolicy.cpp的代碼，會分別調用
vendor/mediatek/proprietary/hardware/mtkcam3/3rdparty/scenario_mgr.cpp的
get_streaming_scenario函數和get_capture_scenario函數。它們會讀取一個scenario的feature配置表，遍歷所有的feature，決定哪些feature會被執行。這個配置表中有許多的scenario，一個scenario可能對應多個feature。因此添加自定義feature后，還需將自定義的feature添加到配置表中。MTK feature 對應的配置表是 gMtkScenarioFeaturesMaps，customer feature 對應的配置表是 gCustomerScenarioFeaturesMaps。

vendor/mediatek/proprietary/hardware/mtkcam3/3rdparty/customer/customer_scenario_mgr.cpp：

diff --git a/vendor/mediatek/proprietary/hardware/mtkcam3/3rdparty/customer/customer_scenario_mgr.cpp b/vendor/mediatek/proprietary/hardware/mtkcam3/3rdparty/customer/customer_scenario_mgr.cppold mode
