具有中繼功能之LoRa圖像傳輸研究
為了解決jpeg 的問題，作者張冠鈞 這樣論述：
在物聯網(IOT)的應用中，以公里為單位的長距離圖像傳輸的研究日益增多，但當進行長距離圖像傳輸的過程，有可能會被高大的建築物或障礙物給阻擋，導致封包遺失和接收不到的情況，因此需要中繼節點來避開被阻擋的路徑。如果使用Wi-Fi來進行遠距離傳輸圖像，會消耗大量的功耗，而且只適合短距離傳輸；藍芽(Bluetooth)雖然是低功耗技術，但只適合短距離傳輸。而LoRa(Long Range) 是一種低功耗、廣域網路的無線傳輸技術，因此在本論文中我們使用LoRa來當作長距離圖像傳輸的技術。在本研究論文，我們主要使用樹莓派搭配LoRa來設計圖像之多重跳躍傳輸(Multi-Hopping Transmiss
ion)。我們首先提出利用不同展頻因子(SF, Spreading Factor)的訊號之間會互相正交的特性，來設計一個可以同時發射與接收的中繼器，以減少傳輸延遲及封包碰撞，圖像格式使用JPEG圖像壓縮及16進制編碼，中繼器內部使用MQTT進行通訊。此外為了在同一時段平衡各中繼節點的負擔，避免中繼節點的閒置時間過長，在開始傳送前，我們也首先提出把圖像依不同比例來分割，分批進行傳送較小的圖檔，如此便可減少中繼節點的閒置時間，進而降低整體傳送時間，影像感測與發射節點實際測試的位置在台中市大里區大峰橋上，接收節點設置在朝陽科技大學人文大樓9樓，在這二點之間的距離約為2公里，兩者之間因有遮蔽物擋住，故
無法直接通訊，中繼節點設置在發送端和接收端之間為視線(Line-of-Sight)的情況，中繼節點數目為N，我們進行N=1、2及3及不同圖像切割率(Cutting Ratio)的情形下的實驗，實驗結果發現進行圖像切割時，確實可以把傳送時間降低，而且當切割率=1/(N+1)時，有最佳的狀態，可以得到最低的傳輸時間，結果顯示透過中繼節點，在不被遮蔽物擋住的情況進行圖像傳輸，使用LoRa進行多跳傳輸圖像是可行的。

植基於邊緣偵測與最低位元取代之資訊隱藏技術
為了解決jpeg 的問題，作者吳苔秀 這樣論述：
本研究提出一種運用邊緣偵測及最低位元取代的資訊隱藏方法。此方法藉由人類視覺系統無法察覺影像細微變化下，於影像中藏入秘密訊息，以高斯拉普拉斯邊緣偵測法（LoG）及最低位元取代法（LSB）為基礎進行藏密，不僅提高藏密量，同時也能確保藏密影像品質。藉由將載體影像切割成連續不重疊4\times4區塊的方式進行運算，並選定左上角第1個像素為基準像素，經由LoG運算後若此區塊判斷為邊緣區塊，則每一像素嵌入5bit密文，若為非邊緣區塊則區塊內像素嵌入4bit密文並將邊緣訊息標記於基準像素中。以Lena載體影像為例，藏密量與2014年Tseng和Leng學者、2017年Bai等學者及2018年Ghosal等
學者相比增加39.6%、7.3%、與42.7%。並以BossBase影像資料庫進行廣泛性測試，其藏密量為1,088,073位元，與2014年Tseng和Leng學者、2017年Bai等學者及2018年Ghosal等學者所提出方法之藏密法相比增加33.9%、2.7%、36.1%，且仍維持可接受的影像品質。
