Automated measurement of species and length of fish by computer vision
نویسنده
چکیده
Trials of a computer vision machine (The CatchMeter) for identifying and measuring different species of fish are described. The fish re transported along a conveyor underneath a digital camera. Image processing algorithms: determine the orientation of the fish utilising a oment-invariant method, identify whether the fish is a flatfish or roundfish with 100% accuracy, measure the length with a standard deviation f 1.2 mm and species with up to 99.8% sorting reliability for seven species of fish. The potential application of the system onboard both esearch and commercial ships is described. The machine can theoretically process up to 30,000 fish/h using a single conveyor based system. 2006 Elsevier B.V. All rights reserved.

Identification of selected monogeneans using image processing, artificial neural network and K-nearest neighbor
Abstract Over the last two decades, improvements in developing computational tools made significant contributions to the classification of biological specimens` images to their correspondence species. These days, identification of biological species is much easier for taxonomist and even non-taxonomists due to the development of automated computer techniques and systems. In this study, we d...
متن کاملField Programmable Gate Array (FPGA) Based Fish Detection Using Haar Classifiers
The quantification of abundance, size, and distribution of fish is critical to properly manage and protect marine ecosystems and regulate marine fisheries. Currently, fish surveys are conducted using fish tagging, scientific diving, and/or capture and release methods (i.e., net trawls), methods that are both costly and time consuming. Therefore, providing an automated way to conduct fish survey...

For the purpose of sustainable exploitation of the fishery resources of Oni River, Ogun State, Nigeria, the fish biodiversity assessment was carried out. This was conducted by enumerating and identifying fish species composition, measuring the fish length, fish weight, assessing the fish abundance and biomass, determining the length-weight relationships and the length-frequency of the fishes. A...
متن کاملAutomated Techniques for Detection and Recognition of Fishes using Computer Vision Algorithms
Automated recognition and classification of fish and other organisms is beneficial to efforts of counting fish for population assessments, for describing associations between fish and habitats, or monitoring ecosystems. In this work, we summarize current efforts to automate the process of fish detection and recognition from a video or still camera source using computer vision algorithms. In ord...
متن کاملLength-weight relationship and condition factor of seven fish species from Shahrbijar River, Southern Caspian Sea basin, Iran
Length-weight relationship and condition factor were estimated in seven fish species, including Barbus cyri, Capoeta gracilis, Alburnoides eichwaldii, Pseudorasbora parva, Ponticola cyrius, Cobitis keyvani and Acanthalburnus microlepis from Shahrbijar River, Guilan Province, Iran. A total of 416 specimens ranging from 18 to 135 mm in total length and from 0.06 to 19.25 g in total weight were co...
