fast recognition playing cards In my project, I need to recognize the playing cards (poker cards) which run at a speed of 10 cards per second in front of a web cam. The project can be developed on platform Windows 10 64-bit or on platforms type RASBERRY PI or UDOO or another. If your choice is platform Windows 10 64bit, I prefer use the open CV library. However, it is not excluded the possibility of using other libraries, and / or other languages if the use of these alternatives is strongly motivated. If your option is to develop on embedded platforms, it offers freedom of choice in the use of libraries, language as long as it is respected recognition speed. The possible problems regarding the intensity of light for the recognition of the cards are not to be considered as impacting the brightness is fixed and still adjustable. A sample video is attached to show the speed sliding of cards. 18 C Programming, Android, C++ Programming, Pattern Matching, Raspberry Pi Mar 22, 2017 Mar 22, 20173d 13h $311

network switch software API I'm trying to create a network switch software on a Linux-base operating system.(Ubuntu and Centos are preferred) I'm using C++ to write a parallel software to improve the switch speed. at the first I need an API that helps me to receive/send raw network packets and encapsulate/decapsulation the packets. the following is all I need: *API can run on a virtual machine (currently I run ubuntu on VMWare) *The API can communicate with many network adapters. (eth0, eth1,...) *API Source code and documentation. *API must ensure the receive packet in correct. (check CRC) *API must have some functions/event like these: //InPortNumber: means input port, for example 0 means eth0. - event OnPacketReceived(int InPortNumber,byte[] SourceMacAdd,byte[] DestinatioMac,byte[] Packet) //send raw packet out from OutPortNumber, for example eth1. - int SendPacket(int OutPortNumber,byte[] SourceMacAdd,byte[] DestinatioMac,byte[] Packet) //returns an error code. '0' means success -int GetPacketType(byte[] packet) //returns => 1:TCP , 2:UDP,... these two function and the one event in more important, other functions can be added to the API. 13 C Programming, Linux Mar 22, 2017 Mar 22, 20173d 7h $442

Compile a Debian Kernal We are looking for a Linux Kernel Developer, ideally with experience of the Freescale [url removed, login to view] ARM926EJ-S core. The current project is to solve a hardware issue on the Embedded Arm TS-7670 Rev D (256MB) units using U-boot. Hardware being used: [url removed, login to view] We are currently seeing an issue where the Freescale FEC PHY driver [SMSC LAN8710/LAN8720] on the 4.4.1 kernel has a “flapping” (repeated up/down state on the Ethernet adapter) issue with a small percentage of the devices. The current image being used is: [url removed, login to view] The project is to either recompile or compile from scratch a kernel that fixes the “flapping” issue and produce a working image for the TS-7670 Rev D units. There are new versions of the [url removed, login to view] MAC+FEC driver+SMSC PHY that can be attempted. It would be preferable to continue on Debian Jessie but a build based on any of the RedHat variants would also be acceptable. The manufacturer provides a Debian Wheezy image with the [url removed, login to view] kernel that has this driver issue solved. Taking the driver from this source, recompiling the 4.4.1 kernel with this driver and rebuilding the disk image would be the most preferable route. If required by the developer, a current stable or longterm kernel can also be used. 15 C Programming, Linux, Debian Mar 22, 2017 Mar 22, 20173d 4h $296
