The prosperity of image retargeting technique leads to the significant need of effective approaches for assessing different image retargeting methods. In this paper, we propose a novel automatic approach providing human perception based image retargeting assessment by measuring salient region similarity between the original image and the target image.(More)
Automatic detection of salient objects in images attracts much research attention for its usage in numerous multimedia applications. In this paper, we propose a <i>saliency fusion and propagation strategy</i> based salient object detection method for RGB-D images, in which multiple cues are fused to provide high precision detection result and saliency(More)
Image retargeting aims to avoid visual distortion while retaining important image content in resizing. However, current image retargeting methods usually fail in difficult situations, such as complex structures and intricate arrangements of objects. In this paper, we propose a novel image retargeting approach, which provides low visual distortion(More)
Bag of features (BoF) provides an effective and efficient representation for object tracking in video sequences. However, hard assignment used in BoF generation inevitably brings in quantization errors, which may lead to inaccuracy even failure in tracking. In this paper, we propose a novel soft-assigned bag of features tracking approach (SABoF), which can(More)
Objective. To find a convenient and efficient way to isolate MSCs from human menstrual blood and to investigate their biological characteristics, proliferative capacity, and secretion levels. Methods. MSCs were isolated from menstrual blood of 3 healthy women using adherence. Cell immunological phenotype was examined by flow cytometry; the adipogenic,(More)
Current tone mapping technique for high dynamic range (HDR) image is limited by the gray scale of display screen. In this paper, we propose a novel tone mapping approach based on edge preserved dithering, which makes use of high resolution of display screen to breakthrough the gray scale limitation. To each HDR image, we first decompose its L* component to(More)
