Loudness meters [CAT]

These slides are part of a conference that we gave about loudness (link). Different views of loudness were explained in that conference: Introduction by Llorenç Gómez (TVC) Standards by Josep Ramon Casas (UPC) Loudness meters by Jordi Cenzano (8TV) Loudness in production chain by Emili Planas (Mediapro) The conference was organized by Consell del AudiovisualContinue reading “Loudness meters [CAT]”

Design and implementation of a loudness monitoring system – MERIT master thesis

This paper was created in 07/2013 as MERIT master thesis (from UPC university). The main objective is to explore the normalization of audio levels in the media industry, which is a relevant issue nowadays. Many broadcast organizations around the world are concerned about this problem and they have published many papers and standards that are analyzed in this project, some of thoseContinue reading “Design and implementation of a loudness monitoring system – MERIT master thesis”

Shape from silhouette and camera model slides

This slides explains how to calculate the camera intrinsics matrix, camera extrinsics matrix, and camera projection matrix from camera model. And you can find an introduction of SFS (Shape From Silhouette) method.

Object labeling in a multicamera environtment

In this paper I describe an algorithm that it can relate objects from different images of the same scene. This algorithm needs like starting point the mask images from N full calibrated cameras. The algorithm is able to identify different objects presents in the scene and it can correlate these objects from one picture toContinue reading “Object labeling in a multicamera environtment”

Comparative of different block search methods in the block matching algorithm

This work was done under Coding and Transmission of Multimedia Contents subject of Merit Master (UPC). This work is a comparison of different techniques of block matching algorithm (BM), the BM  algorithm is commonly used in image coding. In this work I implemented the BM algorithm using Matlab, and I evaluate it using different search methods.
