Automatic detection of neurons, astrocytes, and layers for NISSL-stained mouse cortex We present an image processing algorithm for automatic detection of cortex layers and cells from optical microscopy images for Nissl-stained mouse brain. For every layer of cortex we automatically detect a shape and localization of following cortex cells type: neurons of molecular layer... |

From contours to ground truth: how to evaluate edge detectors by filtering Edge detection remains a crucial stage in numerous image processing applications. Thus, an edge detection technique needs to be assessed before use it in a computer vision task. As dissimilarity evaluations depend strongly of a ground truth edge map, an inaccurate datum in terms... |

Digital transmission of subjective material appearance The digital recreation of real-world materials has a substantial role in applications such as product design, on-line shopping or video games. Since decisions in design or shopping are often driven by qualities like “softness” or “beautifulness” of a material (rather than its photo-accu... |

Multiview layered depth image Layered Depth Images (LDI) compactly represent multiview images and videos and have widespread usage in image-based rendering applications. In its typical use case scenario of representing a scanned environment, it has proven to be a less costly alternative than separate viewpoint encoding.&... |

Low cost rapid acquisition on bidirectional texture functions for fabrics Creating photo realistic images from real word complex materials is a great challenge: the reflectance function of materials, especially fabrics, has glossy or specular highlights, reflectance anisotropy and retroreflections. This increases greatly the complexity of rendering. Bidirectional Texture Functio... |

Soft shadow computation using precomputed line space visibility information Shadows are one of the most important effects to create realism in rendering. Most real-time applications use some sort of image based technique like shadow mapping. While these techniques are quite fast, they often struggle at rendering realistic and accurate shadows of area light... |

Micro-expression detection using integral projections Automatic detection of micro-expression from a video is the first step in the micro-expression analysis. In this paper, we present a method addressing the micro-expression detection problem based on the differences in the Integral Projection (IP) of sequential frames. The method can det... |

Accelerating discrete wavelet transforms on parallel architectures The 2-D discrete wavelet transform (DWT) can be found in the heart of many image-processing algorithms. Until recently, several studies have compared the performance of such transform on various shared-memory parallel architectures, especially on graphics processing units (GPUs). All these studie... |
