Detecting copy-move forgery regions through SIFT and region growing strategies
, 2018 碩士數位相機及智慧型手機已成為生活中不可缺少的部分，因此我們隨處可見數位影像，但由於數位化資料擁有容易修改的特性，且影像處理軟體功能日益強大的狀況下，往往可以記錄真實事物的特性面臨極大的考驗。 本論文以區塊擴張及SIFT特徵點之使用來探討區塊比對的複製移動竄改偵測技術，先使用SIFT關鍵點內的資訊作為特徵點的提取及角度的計算，再利用SIFT的關鍵點位置，對影像以9 9大小進行擷取，並進行特徵提取進行，若在於門檻值之內，就以同心矩形的方式依序擴大，再來進行小範圍的區域擴張，使得偵測的圖形可以更加完整 ...

FEBS Letters, EarlyView.Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research
FEBS Letters, EarlyView.What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

Fast copy-move forgery detection algorithm based on group SIFT
Tongxin xuebao, 2020 Aiming at the high computational complexity of the existing copy-move image forgery detection algorithm,a copy-move forgery detection algorithm based on group scale-invariant feature transform (SIFT) was proposed.Firstly,the simple linear iterative ...

Copy-Move Forgery Detection and Localization via Partial Audio Matching
, 2022 Paper Nr.24In this paper, we present a new approach for detecting and localizing copy-move forgeries within digital audio recordings. The approach is based on an audio fingerprinting and matching algorithm that was originally designed for partial audio ...

PENGEMBANGAN METODE BLOCK MATCHING UNTUK DETEKSI COPY-MOVE PADA PEMALSUAN CITRA
JUTI: Jurnal Ilmiah Teknologi Informasi, 2017 Pemalsuan citra dengan maksud menutupi sebagian objek pada citra dengan blok lain pada citra yang sama disebut dengan copy-move. Deteksi copy-move pada citra dapat dilakukan pada domain spasial melalui pengolahan pada tiap pikselnya maupun pada domain ...

KDM7A and KDM1A inhibition suppresses tumour promoting pathways in prostate cancer
Molecular Oncology, EarlyView.Treatment resistance is a major challenge for patients with advanced prostate cancer. This study examined an alternative approach to target the major prostate cancer‐promoting pathway by targeting epigenetic factors, whose levels are higher in tumours.

Copy Move Image Forgery Detection using Multi-Level Local Binary Pattern Algorithm
Journal of EngineeringDigital image manipulation has become increasingly prevalent due to the widespread availability of sophisticated image editing tools. In copy-move forgery, a portion of an image is copied and pasted into another area within the same image.

Molecular Oncology, EarlyView.This study shows that lung adenocarcinomas exploit developmental branching morphogenesis to acquire a therapy resistant basal‐like tumour cell state. This process was found to be regulated by combined TP53 loss‐of‐function and type‐I interferon signalling, identifying a novel axis for biomarker and therapeutic target discovery.
