In this program I have calculated the features' range of coordinates in the horizontal axis, as well as on the vertical axis. Notice how on the wide image (\"Two squares horizontal\"), OpenCL's max X (horizontal) value is significantly less than CPU's max X value. Similarly, on the tall image, the OpenCL's max Y (vertical) value is significantly less than CPU's max Y value. Also notice how OpenCL detects less features (actually, half) than CPU does:\r\n\r\n(This is using arrayfire at 8ecbe61)\r\n\r\n```\r\n*** Two Squares Horizontal ***\r\nRows: 400\r\nCols: 800\r\nCPU features: 8\r\nOpenCL features: 4\r\nCPU range: \r\nX: 100,699\r\nY: 100,299\r\nOpenCL range: \r\nX: 100,299\r\nY: 100,299\r\n*** Two Squares Vertical ***\r\nRows: 800\r\nCols: 400\r\nCPU features: 8\r\nOpenCL features: 4\r\nCPU range: \r\nX: 100,299\r\nY: 100,699\r\nOpenCL range: \r\nX: 100,299\r\nY: 100,299\r\n```","author":{"url":"https://github.com/mark-poscablo","@type":"Person","name":"mark-poscablo"},"datePublished":"2018-06-25T17:55:58.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/2213/arrayfire/issues/2213"}
