綜述:圖像計(jì)算傳感器

極市導(dǎo)讀
?本文完整地梳理了圖像傳感器的進(jìn)化歷程。從半個(gè)世紀(jì)前Gene發(fā)明傳感器基礎(chǔ)單元開(kāi)始,圖像傳感器越來(lái)越先進(jìn)和復(fù)雜。它們不再只是能感知光信號(hào)的設(shè)備,而成為主動(dòng)進(jìn)行復(fù)雜處理的計(jì)算傳感器。>>>極市七夕粉絲福利活動(dòng):煉丹師們,七夕這道算法題,你會(huì)解嗎?
1 引子





Integrated arrays of storage mode detectors are suitable for application as image detectors. Under this broad classification are such applications as pattern recognition, print or photo readers , image tracking, and real-time surveillance. 存儲(chǔ)模式檢測(cè)器的集成陣列適合用作圖像檢測(cè)器。在這個(gè)廣泛的領(lǐng)域下,有諸如模式識(shí)別、打印或照片瀏覽器、圖像跟蹤和實(shí)時(shí)監(jiān)控等應(yīng)用。

The RedEye vision sensor architecture extracts ConvNet features in the analog domain to reduce analog-digital sensor readout overhead. The architecture promotes focal plane scalability by localizing design complexity and promotes energy efficiency by analog noise admission. RedEye視覺(jué)傳感器架構(gòu)在模擬域中提取ConvNet特征,以減少模數(shù)傳感器讀出開(kāi)銷(xiāo)。該架構(gòu)通過(guò)本地化設(shè)計(jì)復(fù)雜性來(lái)提高焦面可擴(kuò)展性,并通過(guò)模擬噪聲接納來(lái)提高能效。
