The first paper discusses the privilege concept in visual cryptography.A model is proposed to help the design of the sharing matrices.High privilege participant has better capability to reveal the secret image.The restored image has better contrast t

The aim of stock prediction is to effectively predict future stock market trends (or stock prices), which can lead to increased profit. One major stock analysis method is the use of candlestick charts. However, candlestick chart analysis has usually

Block-based progressive visual secret sharing (BPVSS) is an encryption technique that utilizes the human visual system to recover a secret image. The recovery method is based on building up different image blocks step by step. In the last few years,

The basic (k, n)-threshold visual cryptography (VC) scheme is to share a secret image with n participants. The secret image can be recovered while stacking k or more shares obtained; but we will get nothing if there are less than k pieces of shares b

This research applies the content-based image retrieval (CBIR) technique for stock prediction. In particular, low-level image features, including wavelet texture and Canny edge are extracted from candlestick charts. Then, similar historical candlesti
